histone
Last reviewed 01/2018
A histone is a simple, basic protein which interacts with the DNA double helix to form a nucleosome. There are several types of histone; each nucleosome is derived from 2 each of histone:
- H2A
- H2B
- H3
- H4
Histone H1 facilitates the next level of structure with nucleosomes coiling to produce a chromatin strand.
