Gene Machine: The Lac Operon
phet.colorado.edu/en/simulatio...
In this video Paul Andersen describes the elements of an operon. The promoter allows the RNA polymerase to transcribe the required genes. The operator and repressor regulate the expression of the genes by blocking the RNA polymerase. The genes for a specific task are all located in sequence so that they can all be transcribed at once. He starts be describing how the lac operon can be initiated to break down lactose. He then explains how the trp operon can be activated to create tryptophan. He ends with a simulation of the lac operon.

not all heroes wear capes
+sherrwagn1234 yea, they wear glasses!! haha :)
he deserves a cape
@@kimlynnybaby true
Some wear lab coats lol
Some make UA-cam videos
I'm a medical student without a strong background in genetics. Your explanation was far better than the explanation given by multiple medical school professors.
Jonathan Uhl You’re a Doctor now! How do you like it? Premed here, watching this video helped me to understand lac operon too.
I'm in the same situation. I've been using Bozeman since AP bio and now he's even being a life saver in med school!
Are you a doctor now
Here are some notes too.

@@ChadbourneZitek You're a Medical Student now! How do you like it? Premed here, watching this video helped me to understand lac operon too.
Wow, so in 10 minutes I understood something I've spent several days trying to understand... If only all lectures could be like this.
Do you remember any of this? Lol I feel like I won’t
I swear these college professors purposely make these topics way more confusing than they need to be to boost their egos. This guys explanation is 1000x better....thank you sir
This man has saved my biology grade
Your videos have been the lactose to my lac operon, deactivated the repressors in my brain and allowing the information to FINALLY be understood. Thank you for that.
Even though I watched the Khan academy video, I could not understand it. But this man solved the whole problem in JUST TEN MINUTES
This has been more helpful than any lecture or book for me. As a visual learner, some subjects in biology taught mostly from the text book with the occasional image, has left me with a lack of understanding, only trying to do rote memorization for passing a test instead of understanding the concepts well. The combination of professor presence with simple and effective graphics has been extremely helpful. Thank you.
hey stephen, I bet you passed your class man 😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂😂
My biology teacher showed us animations for several topics (really helpful), but unfortunately not for this topic. Thanks to you, I finally understand it.
Awesome. Thanks for the comment.
You have been my go to guy for two years. Thanks for the B in My College Chemistry class. And thanks for the A I'm going to get in Microbiology. :)
Stephie Woe you got your A?
+Nina Duran We will never know...
yep we will never know
Indeed
Four years later and we still don't know.
you've literally saved my grade in AP Bio
I got a test in ap bio tomorrow lmaoo
I know I'm just repeating what everyone has said thus far, but seriously... thank you so much for this. All your videos have been immensely helpful.
right now u r nothing less than an angel for me. this topic in my textbook just sucked my mind. the video is sooooooo dammnnn awesome, im at a relief now. big thanks.
I'm from Poland and English is not my first language, but actually I understood more while watching this film in English than at school in Polish where we have spent hours to understand this. Thank you so much! ;)
Another video that helped me understand a concept I was foggy on, despite the aid of several resources. Thank you so much, sir!! You are an exceptional teacher and I hope you never stop making these videos.
Watched a lot of your videos in AP Biology in High school and still watch them in college to refresh! Thanks a lot!
lifesaver! i have a test today and had no idea what this concept was about and now it seems so simple! you'll be the person getting me through my final exams!
these videos might not be as exciting as vsauce or crash course but it has helped me pass ap biology. forever grateful
Gotta tell you, PROG saved me. It is pretty much the only way I can remember how operons work. Hope I can remember it for the test on monday :)
hi, med student from PROG here :D
This is just a great presentation….Thank you so much. I was excited about going to my Genetics class to brag about how I finally understand how a Operon works !
You made college General Genetics as easy as high school genetics. Which is a good thing! Thank you.
Monsieur Bozeman, vos vidéos (qui datent déjà de plus de sept ans !) sont le meilleur compagnon de mes cours de biologie. Merci !
You. Are. Awesome. Our AP Biology teacher is on maternity leave and we have a substitute teacher who isn't exactly a people's person. Your videos are one of the reasons why I know I'm going to ace the course. I am eternally grateful.
This is amazing. I have learnt all the factors in class but in pieces that was not able to paint any picture. Your video is so helpful in telling the whole story. Thank you!
Im german and understood this animation better than when my biology teacher explained it...thank you so much!!
+Natalie V same :D i am so glad that my english is good enough to understand this
@@Hungergameslover1312 привет
Dear Mr. Andersen,
You are my hero!!!!!!!! you don't understand how much I love biology NOWWWWW that I found your videos. You Rock!!
-Loyal youtube student :)
I spent hours trying to understand this process by reading the textbook and within 10 minutes of watching this video it all makes sense now. I am so glad I discovered your videos, hopefully will save me a lot of headache and stress during my 8 week Microbiology class.
I'm a neuroscience major and I love so many of your videos! I think you make great analogies, and are entertaining/nice to listen to. While there have been a very slight few instances where I though the analogies were a tad off in other videos, overall, I just want to compliment you and say you are absolutely awesome and a huge help. Thank you so much :)
I enjoy your videos. I am now learning about Operon and was so lost in class. Now I fully understand it. I even drew the diagram that you showed during your presentation. This will be included into my notes. THANK YOU so much.
Have an exam tomorrow, and you have explained this the best so far….thanks
Mr. Paul Anderson.........without your videos its sort of difficult for me to understand biology...
thank u so much!!U ROCK!!!!
i wouldn't have passed any of my tests without YOU!! THANK YOU FOR EXISTING
So helpful! Missed my lesson today and since my bio teacher normally shows us your videos in class, I watched this one and everything makes so much more sense. Thank you!
This is literally one of the most awesome videos I have ever watched! I love it. This video actually answered so many more questions that what it was ment for alone. Thank you!
Extremely helpful! You explain in a way that is unlike books or power points. Thank you so much!
this is way better than the book these videos have blessed my existence THANK YOU THANK YOU THANK YOU
My bio class has killed me this year. You literally just helped me so much! All hail Bozeman!
Thanks a lot for the short and yet clear explanation, and the simulation example! This will help me visualize the lac-Operon and remember tomorrow during the exam.
This is the BEST explaination about this on here!! Thank you so much!! Studying for the MCAT!!
You are terrific. Thank you for taking your time to share your talent with others.
thank you so much. I have a final exam next week. i feel so confident now. God bless you.
You have no idea what you have done for me with this video. Thank you, you saved a life.
I am a bioinformatics PhD student and this was incredibly helpful and eye opening. Thanks for your wonderful teaching.
So simple and well explained. Thank you for making this video. I was finding the lac operon really tricky to visualize in my head.
The reason why so many individuals seek youtube for information is because we are visual learners. We learn better when things are drawn out for us.
Fantastic. It was so hard for me to understand what an Operon was exactly, and this really helped out.
Inducer process. It's called an inducer because lac induces the operon. (Process reduces lac in the end).
Vs.
Repressor process. It's called a repressor because it represses the operon in the presence tryptophan. (Process creates trp in the beginning)
Mr. Anderson,
I want to find you and hug the snot out of you. Other students and I have been posting your videos on our bio class Facebook page to get a grip of what we are being "taught". You make learning fun and obtaining an understanding for the information feels like a triumph. I cannot thank you enough.
-that kid who sucked at bio before your videos
Thank you, Mister Anderson! I’m reviewing for my PCAT and this was super helpful.
Thank you so much my college professor failed me last year and you could replace her with all you great demos! Your awesome!
I am studying for my medicine school entrance exam at the moment and wow - this video helped me so, so much! Within a couple of minutes I learned the different parts of a lac-operon as well as what its use. I didn't learn about it in school before and now I know everything I need about it.
You saved my day! Thank you very, very much!
did you pass..
THANK YOU SO MUCH. ITS 2:05 A.M. I was having so much trouble with this. All I have to say is THANK YOU. THANK YOU. THANK YOU.
This video was super helpful. I thought I had no chance of getting this subject enough to pass my test but with this one video I have hope! Thank you
Mr. Andersen my bio teacher always shows your videos in class. Thanks man.
Thankyou Mr. Anderson, for the great help with your video's over the years, you have the nac for teaching i appreciate it
I just spent 2 days trying to figure this out, in 10min, I am now a master. Thank you
Really appreciate all your videos! thank you for taking so much time in making them. Thank you so much! You bring me through my College.
Mr.anderson,
the way you teach is just awesome! operon seemed really complicated before i saw this video.. now iam sorted out! thank you so much.. you rock sir!
your teaching is very nice and can understand them easily. i see all the topics thought by you for my exam. they are really very useful. thankyou
I am a 12th grader from India. Operon had been killing me since the first term You are a life saver. Thank you so much!
You are the best..simple and to the point!
Thank you
Your videos are awesome. I understand everything a lot better after watching your videos!
Best explanation by a country mile. Thank you!
Thanks so much for the simulator!!
awesome demonstration of the lac operon
this video is so informative and ur animations are amazing because i am a visual person. I wish you were my teacher because ur a great teacher
It was really helpful sir, When I was in my class when teacher was telling about lac operon I had some issues with my friends which made me so tensed and I couldn't even pay attention to the class, but now I know the concept, thanks a lot
Ap Exam in 2 weeks and learning it for the first time with your videos. Thank you! :)
You are a very talented professor. Thank you
I owe you dude I really wish you were my cellular biology professor. Im taking midterms just two or three days later and you saved me
THIS IS AN INCREDIBLE VIDEO! You are a fantastic educator!
My biology class watch your videos and you sir help simplify the most complex things! Thank. You.!
Thank you so much for explaining this concept to me.
Wow! couldn't have it simpler than this!! I have bookmarked a lot of your videos. thanks men.
what would I do without youtube! thanks! your animations and nice explanation helped me a lot.
Thank you for explaining it the way it should be explained, very clear and helpful.
Still in 2020 nothing compares to your videos!!
Gracias from Medellín Colombia. Tomorrow is my final exam on molecular biology….your explanation helped.
YOUR LECTURES ARE SUPERB ! THANKYOU SO MUCH
greatly appreciated all the effort +that behind the scene!! teaching is an art, excellent!
thank you so much for all of your videos. they are so easy for me to understand. I wish you were my microbiology professor
omg thank you, you literally always explain it the way that I understand best.
wow, this helped me so much!! Thank you, your videos are always so helpful, and we really appreciate you!
Nice work. You made it easy to understand. Thanks!
We literally had this topic today... THANKS FOR SAVING MY LIFE!!!!
Great video with great animations, Thank you sir
Great video. I never thought I would understand something like this and you made it possible.
Thank you Mr. Andersen this was a difficult topic to grasp. 🇮🇳
Thank you!! My genetics book is horrifically, terribly, horribly confusing, and this was soooooooooo much better! :)
Thank you sir. You are a very talented Professor and your video really helped me.
awesome experience of learning with you, thanks a lot.
Love all of your videos! Thanks for the help! :)
Thank you SO much!! this was super helpful. Such a clear explanation and love the animation at the end of the video
Thank you so much for this video! I didn't understand it in my teacher's lecture or my textbook, but I do now! great video, very clear and to the point. Thank you!
you are really helping me understanding many concepts
Thanks
Very useful, excellent resource for science (i.e. Biology studies, majors), and effective presentation in the breakdown of information, material, which I shamlessly cut-paste, rip and share in my own science classes. I thank you and look forward to viewing more. You easy-going camera presence, shockingly horrible but always entertaining faux-French pronunciation make the whole package enjoyable...as the French say, "Muy tres bueno mon frere mange la fettucine!"
thank you for making everything rediculously simple!!!!! and science less scary
Very clear and concise, to the point. God Bless
I have passed all my classes because of you
