Each of these tiny beads is a called a nucleosome and has a diameter of approximately 11 nm. The nucleosome is the fundamental subunit of chromatin. Each nucleosome is composed of a little less than two turns of DNA 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 H2A, H2B, H3, and H4.ach of these tiny beads is a called a nucleosome and has a diameter of approximately 11 nm.
