I swear you are right :( I dnno why our lecturers don't explain things like that I feel that they even make things more complicated .. hopefully none of them will notice my comment lol
I have a professor that is impossible. When people in the class ask questions, he never answers them directly. It is so frustrating. Your videos help me so much, and are probably the only reason I am actually passing. Thank you for posting them!
This guy works really well, he straight and to the point and he only takes 9-10 mins to explain things where as in class the instructor takes 40-50 mins of just throwing info at you and you don't really get anything out it. Really I appreciate your videos you obviously know your materials.
See I remember using this video when I was in high school doing AP bio and now I am using it in medical school years later and the quality is still excellent. Thank you so much for your videos and exceptional teaching! Kudos!
Goodness, the most LUCID explanation out there. This is the first time I've heard of this process, and it clicked right away. Thanks so much for putting so much effort into your illustrations, and I'm so looking forward to exploring your other videos in other topics and subjects! I can't thank you enough for your wonderful work!
The inducer-repressor control of the lac operon is an example of ----negative control----, in which expression is normally blocked. In contrast, the CAP-cAMP system is an example of positive control, because expression of the lac operon requires the presence of an activating signal-in this case, the interaction of the CAP-cAMP complex with the CAP region.
You have no idea how helpful this was, I was staring at the figures in this section of my book for a good 15 minutes and didn't understand a thing and you explained it all in 10, thank you!
Dr. Bozeman, you might have it backwards at 6:39 According to Wikipedia lac operon is Negative Inducible -- negative because in it's normal state a Repressor is needed to turn it OFF--and Inducible because expression can be turned back on when induced (allolactose). "The lac operon is a negatively controlled inducible operon, where the inducer molecule is allolactose"
The Lac Operon can be positive or negative but there example you describes as "positive control" is actually negative control because the Lac operon is off when the repressor is active.
I'm from Iraq and I'm studying med in Romania and thanks to you I have so much clarified out so God bless you.A lot of Romanian students are also watching your videos and they're saying it's so helpful to them in bio classes. Bet you didn't know there are overseas viewrs for your videos.Thanks again.
My teacher has resorted to assigning your videos for homework... We worship you in my class; You are AMAZING. Thanks for all the hard work that went into making all these lovely videos.
I was contemplating a change in my major until I stumbled upon your vidoes!! They are very attention keeping (I would know because I am terribly ADHD) and the way you explain everything helps me feel like I could learn anything. I've been pulling all nighters and I still don't want to fall asleep like I do during my lecture. So again, thank you for your videos and all of the knowledge that you have shared with me.
Professor Anderson, your videos have truly been a life savor for me this semester. I'm taking a genetic course online, so I'm unfortunately missing the lectures that I desperately need. But with your videos, I can get the clarification I need that my book can't always convey!
Dude I live in India and in my high school i almost spent a day or 2 just trying to figure out this operon..reading tens of books but still couldn't understand much. I now realise this is what it means to be a teacher how u explained it marvellously! Me being an average student no teacher near me really cleared my doubts but thank you for ur efforts!!❤
Thanks for the info. But i don't think positive regulation is the correct terminology to use for the allolactose binding to the lac repressor. Positive regulation is specifically the binding of an activator to it's regulatory sequence and thereby increasing gene product.
i have a test tomorrow and left my book and notes at school...i'm so glad i found a useful and informative video. i am now reassured! thanks so much!!!
WoW! This video explains the whole chapter in just 10 minutes. It is way better itself than the lecture we had. Thank you very much Mr. Anderson. -Bio major @ Ryerson University
Took me 5pages to read all this and my notes are all over the place. Watched this video and learn it all with no problem - Thanks a lot please post more videos Love how you teach.
My Pre-AP textbook puts this simple process in such complicated words that it becomes hard to understand. The exact same thing that you said is out in my textbook in 25 pages. You are my hero. I guess I don't have to read my book now. You saved my grades. Thanks man :)
honestly the money i paid for this course should be given towards bozemanbiology .................. your videos helped me understand the concept way clearer than the book. Effort highly appreciated. Thanks :)
I have probably viewed over 20 of your videos and have found all of them to be very helpful. I was shocked to see that only 2 people have donated on your website (bozemanscience) I'll be adding my name to that list. Thank you Mr. Anderson.
Thank you so much. Mr. Andersen if all teachers were as talented as you, we would live in different world. Your videos are very helpful and informative!
this guy really is the man.. I always watch his videos before i start a new chapter because he helps understand the basics/foundation of everything then i feel comfortable getting into details in my textbook. Thanks a lot Mr.Anderson !
Both lac operon and trp operon are negative control operons because repressors are involved. However, the lac operon is inducible (induced by allolactose) whilst the trp operon is repressible (corepressor tryptophan).
Also, just to be clear, that article was not my sole source for information, I was just offering it as a resource because I found it to be concise. You do such a great job of explaining, I hope you update and correct this video, because I love your channel and find it to be an awesome resource for students!
that was very helpful Mr. Anderson I'm IMG and I studying biochemistry after more that 12 year , and your video with all the explain graphics really helped me out
Thank you Mr. Anderson, I am in Medical Microbiology and I did not understand this concept by just reading the book. I am so confident that I understand this more . I Love this video that I am going to send it to all my friends and professor to show the entire class.
Great video for clarifying some major aspects of gene regulation. It is almost important to take into consideration the physical state of the chromatin involved in the process for this is another major factor which impacts gene expression.
Thank you Mr. Anderson.. Your teaching helped me understand Gene expression....especially the LAC operon and the functions and movement of RNA polymerase, repressor and the operator.
Thanks a lot ..your videos are so informative and well done.. Lac operon = negative control bc transcription occur only when repressor fail to bind to the operator Trp operon = positive control
I missed some lessons on this but understood everything perfectly thanks to this video! A lot of videos are only good for revision purposes so you only understand them once you've already been taught the topic, but this video was excellent for someone like me who hadn't visited the topic at all.
Thank you so much for your video. It helped me a lot. Now I can understand more about the operon lac. You are a great teacher! Please continue like this! ❤️
i really appreciate your work. you have helped me immensely in understanding biology - sometimes when you're reading pages on pages of text from the text book none of it is absorbed. This interactive video really captures the ideas and concepts the textbook is trying to explain, so thankyou
this was very well explained! i understand everything, also if i english is not my motherlanguage or primary language. which program du you use to make these presentations?
Hi, this video is useful because even my professor in biology class send e-mail to watch this. However, he made a couple of correction from your video, so hopefully it will be helpful for everyone and editor. "making genes" is said a few times in the video when instead it should be "making RNA". Lastly, the mRNA made from the bacterial lac operon is one polycistronic mRNA encoding three separate proteins. It is stated incorrectly in the video that three separate mRNAs are made from the lac operon.
Mr. Anderson, you've just earned yourself a subscriber. You and I are going to become very good friends over the next 7 months! That AP Bio exam is GOING DOWN.
Watched this man throughout high school AP bio and watching him again for my college bio final. This man is seriously the GOAT
im on that first part lets see if i come back for the second half
lol yeah I am learning this for my genetic class currently
I'm in medical school aka the third part and yes, he is incredibly helpful
7899
Same！I just realize I has been watching his videos at different times for 5 years 🤣
Excuseme what gene do I need to activate to get that jawline
Smooth. Flirting with your teacher
FOXP2 Gene
😂😂😂😂😂😂
Checking out mewing. Great vids on UA-cam about it
Lmao
If only my teacher could explain things like this,my life would be a lot more easier! Thank you so much!
Thanks for the great comment. Best of luck with your studies.
I swear you are right :( I dnno why our lecturers don't explain things like that I feel that they even make things more complicated .. hopefully none of them will notice my comment lol

My prof teaches with his videos.
I think some professors actually don’t know the answers so they just say something random.
"...and I hope thats helpful"
Dude...that was WAY more than helpful!
THANK YOU!
This guy works really well, he straight and to the point and he only takes 9-10 mins to explain things where as in class the instructor takes 40-50 mins of just throwing info at you and you don't really get anything out it. Really I appreciate your videos you obviously know your materials.
watching this video is my home work...... shows how much my teacher actually does
amen to that! my teacher doesn't do crap
lmao.
yeet
At least it's a short (and very helpful) video.
I have a good teacher and we still watch these, it's for extra support and also we move too quickly because it's AP to explain everything repeatedly
this guys my teacher in real life for AP Bio...hes so great, its my favorite class of the day.
Tatsko mbn
how did you turn out my man?

Currently cramming for the AP exam and honestly your videos are the only thing keeping me going right now
Of course I remember you. I'm happy to hear that you are majoring in molecular genetics. You will be smarter than me very soon. Let's Go Deacons!
What lol
7 years passed, wondering how Deacons is
he's probably replying to a comment. Deacons are probably the name of the university team name. My mans probably in his early career by now
Ooop whoever had him as a teach is hella lucky

In contrast, the CAP-cAMP system is an example of positive control, because expression of the lac operon requires the presence of an activating signal-in this case, the interaction of the CAP-cAMP complex with the CAP region.
How this guy prepared his lecture is a work of art.
Thank you so much! You explained three first year-bio lectures in a 10 minute video. And it all made sense!
My class got booted onto online AP Bio before our teacher left mid-year. Your videos are so much more helpful than the online course I'm taking.
The Lac Operon is an example of negative control, not positive. I'm confused here lol
You have no idea how helpful this was, I was staring at the figures in this section of my book for a good 15 minutes and didn't understand a thing and you explained it all in 10, thank you!

30 minutes of reading explained very well in 10 minutes...I would like to thank you on behalf of us lost BIO students!
I feel like I could get an A on this, but I still don't truly understand.
this is me with practically all of school
especially math
I couldn't have summed up my school experience better
The Lac Operon can be positive or negative but there example you describes as "positive control" is actually negative control because the Lac operon is off when the repressor is active.
I'm 5 years late but that's exactly what I was gonna say...that was a negative control
I'm from Iraq and I'm studying med in Romania and thanks to you I have so much clarified out so God bless you.A lot of Romanian students are also watching your videos and they're saying it's so helpful to them in bio classes.

I swear this channel saved my life. Idk how i could've gotten through ap bio without this channel. Thank you so much for the help!

Bozeman, your videos helped me through high school freshman bio, AP bio, college bio, and now med school biochem. seriously an amazing resource!!
Thank you SO much. I don't understand why professors can't explain like this. If youtube and people like you didn't exist I'd fail my bio tests
Dude I live in India and in my high school i almost spent a day or 2 just trying to figure out this operon..reading tens of books but still couldn't understand much. I now realise this is what it means to be a teacher how u explained it marvellously! Me being an average student no teacher near me really cleared my doubts but thank you for ur efforts!!❤
You helped me through honor's bio in high school and now you're helping me through bio 1 in college! you're the best!
Thanks! I'm in grade 11 taking AP Bio and I don't understand a word my teacher says!
You saved my life. Thank you!!
r u married
Thanks for the info. But i don't think positive regulation is the correct terminology to use for the allolactose binding to the lac repressor. Positive regulation is specifically the binding of an activator to it's regulatory sequence and thereby increasing gene product.
The lac operon is definitely an example of negative control! Not sure why he said positive
i have a test tomorrow and left my book and notes at school...i'm so glad i found a useful and informative video. i am now reassured! thanks so much!!!
WoW!

i just couldn't listen and had to repeat the video cause i was staring at Paul the whole time... dat jawline....
Why can't my biology teacher just explain everything like this! Very helpful, thank you so much. I love all of your videos.
My Pre-AP textbook puts this simple process in such complicated words that it becomes hard to understand. The exact same thing that you said is out in my textbook in 25 pages. You are my hero. I guess I don't have to read my book now. You saved my grades. Thanks man :)
honestly the money i paid for this course should be given towards bozemanbiology .................. your videos helped me understand the concept way clearer than the book. Effort highly appreciated. Thanks :)
You have literally just taught me more in 10 minutes that my teacher has in a month. Life.saver. :)
it's crazy I was 15 and watching Bozeman for AP bio and now I'm 19 and in Cell Bio and you still help me out! This is amazing thank you!
I have probably viewed over 20 of your videos and have found all of them to be very helpful. I was shocked to see that only 2 people have donated on your website (bozemanscience) I'll be adding my name to that list. Thank you Mr. Anderson.
been watching your videos for two years...always a GREAT help. Thank you so much, Professor!
Thank you so much. Mr. Andersen if all teachers were as talented as you, we would live in different world. Your videos are very helpful and informative!
As a student going for a masters in biochemistry I couldn't do without videos like these. In other words yes it was very helpful.
I KNOW THAT MY TEACHER SUCKS AT BIOLOGY BUT WHEN I CAME THREW THIS CHANEL I GOT A A+
this guy really is the man.. I always watch his videos before i start a new chapter because he helps understand the basics/foundation of everything then i feel comfortable getting into details in my textbook. Thanks a lot Mr.Anderson !
Both lac operon and trp operon are negative control operons because repressors are involved. However, the lac operon is inducible (induced by allolactose) whilst the trp operon is repressible (corepressor tryptophan).
These videos have saved my sanity in my AP Bio class. Keep doing what you're doing, it is so appreciated!
this is the first time i can clearly understand about gene expression, thank you mr.Andersen..may god bless you
If only my teacher could explain things like this,my life would be a lot more easier! Thank you so much!
Better than how my professor was trying to teach, you rock man!
most underrated teacher
You saved my life once again!
Started at 8 tonight. Sleeping after this one. GL to everyone taking the exam!
Idk how I'd get through AP Bio without you
Thank you soo much. My teacher hasn't taught us a thing this year and this is the only teacher I get even if you're online
:) You're an excellent teacher. You've taught me more in ten minutes than my teacher did over the course of ten class periods.
Everytime he said "or not," I couldn't help but to think "OR NAH"
NAWT... I do enjoy my 'O's! But it seems most people do not.
Thank you so very much; I pay big money for "an education", and you explain it better int en minutes than in ten lectures. Thank you!!!
Also, just to be clear, that article was not my sole source for information, I was just offering it as a resource because I found it to be concise. You do such a great job of explaining, I hope you update and correct this video, because I love your channel and find it to be an awesome resource for students!
AP Test tomorrow at 8am.
Started studying since this morning.
On an (Ir)relevant note. Happy Mother's Day! :D
that was very helpful Mr. Anderson I'm IMG and I studying biochemistry after more that 12 year , and your video with all the explain graphics really helped me out
Thank you! My lecturer spent an hour explaining this and I did not understand anything. You made this so simple to understand!
10,822 views, and 28 comments. That's crap. You have a wonderful way of describing things and I hope you understand that your efforts matter.
Our teacher showed us a video of a different guy talking about this today. And I was like, heck no I am going home and watching Bozeman. Loyalty!
Thank you so much. I’ve leaned these educational videos on UA-cam are better than my teacher for biotech.
Thank you Mr. Anderson, I am in Medical Microbiology and I did not understand this concept by just reading the book. I am so confident that I understand this more . I Love this video that I am going to send it to all my friends and professor to show the entire class.
Thank you Bozeman Science for getting me through my biology class!
This video is fabulous. You have no idea how many times I've watched it for my biology final tomorrow. Very helpful :)
I am taking a graduate genetics course, but I come here for the basic explanation. He does a great job
Your videos have literally saved my VCE life! Thanks so much for sharing :D
You are absolutely the best teacher to explain all this things. Thanks for your time and dedication
You just saved my biology exam, that's helpful ;)
Thanks sir. You've done a much better job explaining than my stuttering biochem professor in college.
Amazing explanation, great animation and idea map at the beginning.
Great video for clarifying some major aspects of gene regulation. It is almost important to take into consideration the physical state of the chromatin involved in the process for this is another major factor which impacts gene expression.
Thank you Mr. Anderson.. Your teaching helped me understand Gene expression....especially the LAC operon and the functions and movement of RNA polymerase, repressor and the operator.
Aren't you gonna talk about the cAMP and positive regulation activating the promoter?
That was extremely useful! Thank you so much! I finally get it!
Somehow, you always manage to make everything seem so simple.
Love love loveeeee all your videos!!!! So much more helpful than any other youtubers!!!
Bozeman Science you are giving science from all your heart, that is how our profs. need to do. god bless you man.
Thanks a lot ..your videos are so informative and well done..
Lac operon = negative control bc transcription occur only when repressor fail to bind to the operator
Trp operon = positive control
YOU'VE SAVED MY GRADES, THANK YOU, YOU'RE AMAZING!!!
You are honestly a life-saver!!!! Very helpful, and easily understandable. Thank you so much for your video!

I have an exam tomorrow and this helps a lot. Thank you!
this was very well explained! i understand everything, also if i english is not my motherlanguage or primary language. which program du you use to make these presentations?
Thank you so much for this. I missed this lesson at my school and the textbook was not helping. Now I think I am ready for my test.
Excellent as always. Two classes and three different textbooks couldn't reach me with what only took 10 minutes here.
8:20 Hi Mr. Anderson, Would you do a video on junk DNA? Thank you and best wishes.
You are so much better than my Biochemistry course in-charge.
Gosh! I used to sit in class horrified... staring at those slides. :P
thanks alot :) i have been searching everywhere for this on youtube and your way of explaining this was perfect :)
You make everything so simplified. Thank God for you.
