Question

The histone that links two histone octamers is:

• A. H1
• B. H4
• C. H2A
• D. H2B

Hint:

Understand the role of histone H1 in stabilizing chromatin structure and its association with linker DNA.

Answer 1

The Correct Option is A

Histone H1, often referred to as the linker histone, binds to the DNA that enters and exits the nucleosome core particle, stabilizing the chromatin's higher-order structure. Unlike core histones (H2A, H2B, H3, H4), H1 is not part of the nucleosome octamer but instead associates with the linker DNA between nucleosomes, facilitating chromatin compaction.
