Regulation of Gene Expression: Operons, Epigenetics, and Transcription Factors

It's important not to conflate the prokaryotic gene expression regulation and eukaryotic gene expression regulation. The part about the DNA wrapping around the histone proteins happens in eukaryotic cells (e.g. human cells). The part before then about the operators only happen in prokaryotic cells (e.g. bacteria, and that's distinct from how gene expression is regulated in eukaryotic cells. E.g. eukaryotes do not have operons). Without sufficient explanation, the video seems misleading.

how can anyone know this and not believe in God? the sheer intellect in designing such a complex and effective system - it's unparalleled! HalleluYah!

Professor Dave knows his stuff

Wow so simple

Wow! I was not looking forward to even this 13 minute clip. But, WAS I WRONG. Your presentation is by far one of the best. Again, most of us are visual learners and the animation along with your teaching was spot on and kept me interested and rarely was I lost or confused. Thank you so very much!

thanks professor Dave ! u made my nightly study session a lot more endurable

Thank you so much prof. , colud you please explain gene expression in eukaryotic 🥺please

This is super helpful, but it would be even more helpful if you put in the corner which organisms these concepts apply to, since some of these only happen in bacteria and others in eukaryotes, and still others in both. This is something that confuses me all the time, so if you make more videos along these lines in the future, that would be very informative!

Hello sir, 


Sir, does dna Methyalation is a reversible process? 


Sir, what is mean by, level of Methyalation of a gene is 50%., 


Sir, does it implies that, the gene is 50% expressed or the gene is partially working? 


Thank you sir. 


Yours sincerely

Pritesh Lodh.

God bless you professor, thank you for your presentation.

helpful thnx

Thanks Proff.

Ight finna get that 5 for the AP exam tomorrow

you have described gene expresion with 13 mins dude!!!! our professor couldnt explain it with 1.5 hours or more....

save my life

🐐

Hi Professor Dave, one tiny thing I noticed in this video. When you say that methylation can make the DNA more accessible. It is the opposite, methylation makes the chromatin to coil tighter making the DNA less accessible. Thank you

This was very short and precise. I understand clearly all that he said more than how my professor taught it. Thank you professor 🙏🏽 🤗

thankyou for the explanation

I have a question professor.. If we can find and block transcription factors in some way which are activating proto oncogenes then its a possible way to supress tumours?

He should know exactly how awezome he is😭😭😭✊

SHOWING FEW ANIMATIONS, making students understand regulation of gene expression in 10 minutes. vs teacher speaking this, showing no pictures or vids. and wasting 2 hours on this with 0 effects. GZ

Well done

The textbook descriptions show all the intron RNA being synthesized, then spliced out and simply forgotten. Do we know for sure the discarded intron segments, some quite long,, have no further effects before being degraded?

This is an excellent review!

Excellent explanation, thanks again.

Thanks

Very helpful video!

Thanks alot Professor Dave. Your teaching videos are not just clearing the concepts but arousing the curiosity to learn more about the topics.

thanks professor dave easy to learn 😃😃😃😃😃

This is why younger professors are better, you can sense the enthusiasm

This is truly amazing how complex notions can become so easy to understand when clearly explained. I’m grateful for your channel. Lots of love from France.

ty ily

Amazing sir..💖❤

You seriously CAN'T IMAGINE HOW MUCH I LOVE YOUR YT CHANEL. OMFG, SUCH A GOOD, "FRIENDLY" (easy to understand) AND YET ACADEMICLY SUFFICIENT CONTENT, WOW!
Im an instant new sub, keep up the excelent work!

Thank you for this!

Can you make a video tooth regeneration research and cell inductive capacity for tooth regeneration dr paul sharpe from kings college of london is working on this research.

سبحان الله!

U are great!

I feel so stupid I watched all the other videos previously but it still sounds like you’re speaking a different language to me 😣 bio is killing me
