The nucleosome consists of a core particle of eight histone proteins and DNA that wraps around the core. Chromatosomes, which are nucleosomes bound to an H1 histone, are separated by linker DNA. Nucleosomes fold to form a 30-nm chromatin fiber, which appears as a series of loops that pack to create a 250-nm-wide fiber. Helical coiling of the 250-nm fiber produces a chromatid.
-How many copies of the H2B histone would be found in chromatin containing 50 nucleosomes?
A) 5
B) 10
C) 50
D) 100

Question

Quizplus · Accepted Answer

Each nucleosome contains two copies of the H2B histone, so 50 nucleosomes would contain 100 copies of H2B.
