Answer:
Chimpanzees.
Explanation:
DNA sequence similarity is helpful to determine the evolutionary relationship between the organisms. The evolutionary tree can easily be constructed if the percentage of the DNA sequence similarity is known.
The human shows 98.8% sequence similarity with chimpanzee. The sequence similarity between human and gorilla DNA is 98.4%. This means Chimpanzee are more closely related to humans than gorillas.
Thus, the answer is chimpanzee.

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.
