    Thank you, a really great video. I like the bar code comparison at the end. I think that one of the cerebral challenges to understanding histone and DNA modifications is to recognize, in the first place, why they are necessary and moreover, how they allow so so many genes to be read, written to, read again, erased, written to again, read again, etc, switching genes on or off, or modulated in some way. The mental barrier is because the focus is too close, to see the big picture. If the big picture is explained FIRST, in broad outline, reasons, and underlying principles, then the mind, when focusing on the fine detail can connect it back to the big picture. So for example, if these medications are explained from the outset as 1) allowing the base 'bar codes' of genes to be read to enable new bar codes top to be created and 2) that new bar codes to be read to do the same, then this creates in the listener's mind and expectation of where the details are heading, or where it connects. I hope that makes sense.

    wow! untill you say that the phosphorylated serine or trionine both have negative charge like DNA backbone does and this results in the repulsion between DNA and histone which makes DNA more accessible to transcription factors, I didn't know how phosphorylation and all of these modification methods work. This video was so clarifying.

    We can explain the relaxation of DNA when HAT comes, that could be the fact that the acetylation removes the positive charges of Lysine or Arginine then we have less interaction with the negative charges of the DNA's phosphates.

      Shabnam Khatoon Any molecule, critical for the survival of the organism, is highly conserved.In evolution An organism with aberration in chromatin will not survive or rather not selected. organisms with mutations in histone coding DNA does not survive. In other words, only organisms with perfect histone structure will be selected and get evolutionary advantage
