Which histone core octamer composition packages eukaryotic DNA into a nucleosome particle?
Answer and explanation
Correct answer: B. Two copies each of histones H2A, H2B, H3, and H4
The nucleosome core particle consists of an octamer containing two copies each of H2A, H2B, H3, and H4 wrapped by ~147 base pairs of DNA. Histone H1 is the linker histone that binds entry and exit DNA externally.
