DNA Part 14 - The Processing Stage of DNA-RNA Transcription
ive never understood splicing until hearing you explain it, my MCAT is in 9 days. THANK YOU!!!
Jennifer Gibbs how was your test
Good luck on your MCAT!
How did the MCAT go?
You must have been feeling the heat😅
The fact that these videos are so bite-sized while being so informative is what makes me watch these videos so eagerly.
Thank you! Glad they were helpful :)
I have an AP bio midterm tomorrow, in 10 minutes I've understood 60 slides that will be tested on the exam. Thank you so much!
I don't think I'll ever really finish watching this video. I keep cracking up at 'snurps'!
SNURP!
You are so gifted at explaining all the topics in your channel. Thank you so much
Took my lecturer 1 hour to explain this, and I still didn't get it. Thank you so much!
Great video! Just a note; mRNA processing occurs co-transcriptionally (beginning with the addition of the 5' cap). Also, the PolyA tail is added before splicing occurs.
Hello, i want to make sure if i understood so poly A tail comes first then 5' cap along with splicing?
I can’t learn because of your pretty smile >
It's all love here!
Why is it so hard to find a video where someone takes a normal sequence template strand and goes through it in order, identifying exons and introns and showing the mature mRNA?
I'm not going to be a medical student, but I'm in my first year of a biology major and with zoom school, the first two weeks I missed everything important. In hs bio, I slept through it completely. It's taken me 11 minutes to learn something that's taken me 3 years to learn. These videos are the best in terms of content. Never too much in depth so I don't understand, but never to the point it's too vague either.
Yup, same here. Those Amoeba sisters' videos only go so far lol 😩
I am from India and tomorrow is my biology 1st term examination. Your video helped me a lot!
Thank you sir!
You're welcome! Best of luck!
The best! I wish I had a teacher with similar talent as you doc, then I get a better grasp of fundamentals and complex principles of Pharmacy in general especially Pharmacology and Therapeutics!
Thank you so much, you achieved what both my associate professor and professor failed to do. Much love from Iraq
Where was this guy all my life?!?! It's fantastic, I finally could understand this whole process!! Thank you sir!!
We're here now! Glad to hear you've gotten the concept now! You're welcome :)
Best teacher in youtube! ❤️
thank you
Thank you so much. These are extremely helpful, while being concise.
You're most welcome!
Thank you for this! But I have one question, I don't understand why mRNA needs to be processed before leaving the nucleus? Is it to ensure that it doesn't degrade? I'm not sure...can someone please help
You are amazing!!!!!! Thank you sooo much for this very informative content you have.
You are so welcome!
thank you so much . pls i need an explain for the term degrading. is it like the sequence/strands destroyed or dissolving away or something? 😅
Really nice explanation! Thank you 🙂 New sub!
5:20, why are they called EXOnucleases? I thought he was going to say because they begin at the end of EXOns, but he didn't say it.
Such a great speaker. Really appreciate the steady and clear presentation!
Thank you very much, I don't know what I'd have done without your videos, well and clearly explained, you made it look like a simple subject, thank you.
Thank you!!! Glad you enjoyed them :)
nice vid!! thank you very much. but is it homogenous nuclear rna or heterogenous nuclear rna?
SnRNA is the small nuclear RNA instead of the short nuclear RNA
small nuclear rna
Yes :)
Thank you sir your videos are too good.
Glad to help!
I did not understand this the first time I was taught. thank you thank you
This man just saved me. Thanks
just explored the channel and loved it
and then she recommended this channel to me..I ALSO LOVED IT even though this topic is too hard. Thank you so much!
Teachers are so different! You are the one who is destined to be it!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Every thing of you is perfect! frankly perfect! Amazing bro! please make more vedios.. Views may gradually come.
You're Handsom & Smart 🧠🥰
God Bless you, hope you're doing erll
Saving my ass on a regular basis thank you

best mcat video prep I've watched!
Thank you! Please feel free to share them with your school's pre-health group!
I'm a student of class 12th from India and going to attend HS final exam of State Board.....i well understood that topic...Thank u sir
Some basic principles need to be clarified. The direction of translation and transcription 5 to 3. Is every piece of DNA used only in one gene or can be used in more than one gene , I mean example a sequence of DNA (TGATCGCTCATCTC) at site X? of chromosome 1 . Can be part of gene X? and gene Y . Is the anti-sense side of the DNA also used as part of the genes ?
SUCH. AN. AMAZING. VIDEO. !!!!!!!!
Splicing was hard to comprehend. Although I watched a lot of videos about it, yours is greatest.
Im kinda confused my book shows that addition of 5’ cap and poly A tail happens before splicing?
HT M even me🤔
It would make sense for the splicing to occur first, because what if there is an intron at the beginning or end of the pre-mRNA?
God bless you
I love the trick to memorize ❤❤❤❤
why are you not my professor?
Absolutely understandable.
Awesome!
how does the mRNA leave the nucleus? is the 3' or 5' end the "front-end"? 🤔
Really clear explanation
thank you so much
My final genetics exam is tomorrow and thanks to you for making transcription make sense now!
Thank you very much for your explanation 🙏🙏
thanks a lot
guys i just wanted you to know that this is stilll happening in the nucleus. dont get confused
you're amazing man! mcat in 2 months. you been getting me through content
The best video, I've ever seen. Thank you so much.
tnx
Vitamin
F Kaplan, this is way better!
It's all love! XD
HnRNA stands for heterogenous or homogenous?
Thank you I finally understand it.
thank you! This is very helpful
if only my professor explained like this
Your videos are great. Thank you
Now, I understand gene expression
So exellent
Clearly explained. Good job.
Thank you! :)
i love this man , thank you
Wooow thanks!
You're welcome!
Nice explanation sir
Awesome lecture 👌
.
2:41 Why introns are preserved throughout its generations?? Can justify that statement sir?
DNA is passed on to the preceding generations. The DNA that is passed on will determine what RNA is transcribed from that DNA. You never hear about "RNA replication" because DNA contains the instructions for RNA. Conserve DNA, and you conserve the RNA which can be produced from it.
RNA is not directly passed on to future generations.
Maybe a better answer to your question is Alternative Splicing. Look that up, I think it is your answer.
Good videos!
Good work .GOD bless you
Thank you!
This is the best genetics video I have ever found. Excellent explanations！I subscribed right away.
Welcome aboard!
@@PremedHQ You are such an elegant and knowledge gentleman, I like you !
