Explanation / Answer
The histone tails are sites of post-translational modification.
Nucleosome is a fundamental subunit of chromatin. Each nucleosome is composed of DNA that is wrapped around a set of eight proteins called histones, which are known as a histone octamer. Each histone octamer is composed of two copies each of the histone proteins, i.e, H2A, H2B, H3, and H4.
