Answer:
The correct answer is option b. "20 H1, 40 H2A".
Explanation:
Chromatin is a complex that protects and condenses the genetic material comprised of DNA and proteins. When chromatin is in the form of a 30 nm fibril, nucleosomes have a regular positioning along the DNA. This means that each nucleosome is associated with a single H1 molecule. Therefore a chromatin containing 20 nucleosomes will have 20 copies of H1 and 40 copies of H2A, because each nucleosome has 2 copies of the core histone H2A.
