Question

The core nucleosome is composed of two copies each of 4 histones. Which of the following is NOT one of the core histones?

1) H2A
2) H2B
3) H3
4) H4
5) H5

Answer 1

The core nucleosome is composed of two copies each of 4 histones: H2A, H2B, H3, and H4. H5 is not one of the core histones.

Step-by-step explanation:

The core nucleosome is composed of two copies each of 4 histones, which are basic proteins containing many lysine and arginine amino acids. The histones are H2A, H2B, H3, and H4. Therefore, H5 is not one of the core histones.
