Q

Which histone protein is not part of the core nucleosome structure?

A) H1

B) H2A

C) H2B

D) H3

E) H4

A

The nucleosome is the simplest structural unit of DNA packing, and the core is made up of proteins. The nucleosome core is made up of 8 different histone proteins, arranged in different patterns, around which Aa DNA segment is wrapped or wound.

The histone proteins that make up the nucleosome core are H2A, H2B, H3, and H4, occurring in doubles. HI protein, however, is not a nucleosome core histone protein.
