Delicious...

This is the clearest explanation of epigenetics I've seen yet! Thanks for making it

Really well explained. I just wanted to ask, if acetylation positively charges and DNA is negatively charged, shouldn't the structure become tighter?

perfect!

Excellent stuff

Excellent, didactic presentation! Thank you

God is so big without him no one would be here or live including everything He made.

Evolution did it 😀

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.

Please! the histone methylation and DNA methylation occur together or separately in epigenetics?

the nucleosomes depicted here have a right handed DNA turn, and it should be left-handed turn.

Very helpful. Well done.

Those stick diagrams contains billions of atoms and they all interact perfectly with one another. Seems like intelligent design to me; designed by God.

it was really helpfull😍👌

Does anybody know where the second part to this video is?

bs

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.

Thank You

All the information required to create an organism is not in the DNA. Centromeres, other structures, and potentially other codes are required. Cell division will occur without DNA to create hundreds of cells, but of course these are non-functioning. Check on the state of research in a decade, and you may find that oragismal information is much more diversified.

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

Very well described. Thanks alot.

Thank you for this wonderful animation. It makes the concept of gene expression or suppression much beter to understand.

Thank you!! This tutorial has benefited me greatly.
