Question

Histone proteins in nucleosome are:

• A. $H2A,H2B,H2C,H2D$
• B. $H2A,H2B,H3,H4$
• C. $H1,H2,H3,H4$
• D. Pepsin, Rennin, Creatin, Trypsin

Answer 1

The correct option is B $H2A,H2B,H3,H4$

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.
