If it boggles the mind of one attempting to learn how they work, it must have required a mind of unfathomable capacity to design these systems to begin with.
What do you mean at the acetylation part? It stated that when acetylation takes place, it reduces the positive charge of histone tail hence, repels the DNA negative charge. How can that be? Isn't it unlikely to repel if it less positive? And ain't repulsion of the negative charge DNA strand only happen when the positive charge is stronger? Any clarification on this? Thanks in advance.
Excellent presentation. Thanks. But I ask. Are we meant to believe this breathtakingly sophisticated system evolved over millions of years!!?? How does the epigenome mutate? And a beneficial mutation in the genome must be simultaneously accompanied by its epigenetic equivalent for the magic to occur. Sounds very deus ex machina to me.
I too am troubled by this. Despite the standard and valid refrain that we simply can't conceive of large numbers, such as in trying to imagine a progression of changes over hundreds of millions of years, it all seems so wildly improbable. But then here we are. So, WTF is going on? Sorry but, nobody knows or ever will, deal with that.
Those stick diagrams contains billions of atoms and they all interact perfectly with one another. Seems like intelligent design to me; designed by God.
This is the clearest explanation of epigenetics I've seen yet! Thanks for making it
Excellent, didactic presentation! Thank you
Thank you for this wonderful animation. It makes the concept of gene expression or suppression much beter to understand.

Excellent stuff

Very helpful. Well done.
Delicious...
Really well explained. I just wanted to ask, if acetylation positively charges and DNA is negatively charged, shouldn't the structure become tighter?
Very well described. Thanks alot.
Hey if you want to have bleach and put it in your dna say which dna
perfect!
Thank You
Does anybody know where the second part to this video is?
it was really helpfull😍👌
Thank you!! This tutorial has benefited me greatly.

Less positive also means that it becomes more negative, leading it to repel the negative charge of DNA (as negative + negative = repellence).

Nice
Please! the histone methylation and DNA methylation occur together or separately in epigenetics?
Evolution did it 😀

I never understood what gene is expressed instead of a gene that's turned off. It can't be nothing...
