Re:RNA demethylation increases rice and potato yields 50% by KirillPanov on Friday July 23, 2021 @12:26AM (#27927196)
I can't explain the paper, but if DNA is genetic ROM, methylation is like one bit of RAM available on each digit [*].

Most of the cellular machinery tries pretty damn hard to make exact copies of DNA. The methylation bits, by contrast, get deliberately flipped on and off all the time.

[*] Technically only A and C can accept methylation, but in a double helix you'll always have either an A or a C on one side or the other at every position (A pairs with T, C pairs with G).

Deliberately flipped based on what?

That is an area of very active research.

I mean the exact chemical mechanism for the flip is some enzyme, and the flip certainly affects gene expression. As to why the cellular systems flip these bits, great question :)
