Regulation of Gene Expression: Operons, Epigenetics, and Transcription Factors
We learned about gene expression in biochemistry, which is comprised of transcription and translation, and referred to as the “central dogma” of molecular biology. But how is this process regulated? How does a cell know which genes to express and when? Well it’s pretty complicated, but let’s just get our feet wet by looking at operons, epigenetics, and transcription factors!

He should know exactly how awezome he is😭😭😭✊
Hi Professor Dave, it's a bit late but at 9:38 your acetyl and methyl group are labelled the wrong way round 🙂
Edit: Just seen a comment further down addressing this.
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.
What happens to the introns, once removed by the spliceosome?
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.

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
Jesus Christ explaining science 🤯🤯🤯
it is not a fetus but a human
good one
Another wonderful session, thanks a ton
Really perfect explanation! I have a question, so only e.coli has operator to turn gene transcription onoff, is there also operator in human?
I've graduated HS and passed the need to study these (taking econ in college) but i still remain loyal to watching dave
But what regulates the regulators?
this is help me a lot. amazing
Where can i get your transcription & translation videos pls or if any one could send to me the link of it please 😊
I am pretty sure I learned recently that methylation silences genes, esp with the formation of methyl bound domains and CpG islands from a khan academy video. So I don't know what that is about 9:40
8:25 also, just know trp operon MAKES tryptophan, and lac operon DIGESTS lactose. Should be able to figure out the rest. ALSO, the most confusing stuff begins at 10:36.
3:05 & 8:59 although this video isn't over that info, that diagram is way wrong. The right lung has 3 lobes. The left lung has 2. Still great content!!
Professor kindly you may help me how to identify TF of my gene sequences or TF of my genes motifs
