WebSep 13, 2024 · The complex formed by proteins and DNA is called chromatin. Tight wrapping of DNA around histones prevents its access to various chromosomal regulatory proteins, leading to gene silencing. WebAug 30, 2024 · Readers are the proteins that detect and respond to these modifications, causing the DNA to be more or less tightly wrapped around the histone protein. Any of these proteins could be inhibited or activated to affect changes in epigenetic modifications. Old School: Writing and Erasing
