Chapter 15, Problem 19CONQ

Summary Introduction

To review:

The loosening of chromatin packing by the acetylation of core protein.

Introduction:

The histone proteins that include sumoylation, ubiquitylation, phosphorylation, methylation, and acetylation having covalent PTM (post translational modification) are called histone modification. The recruitment of histone modifiers and alteration of chromatin structure impacts the gene expression, which are a part of histones formed by PTMs. In chromosomes, histone protein wraps around 8 histones.
