Question

Histones are enriched with ______.

Options

• Lysine and Arginine

• Leucine and Lysine

• Phenylalanine and Leucine

• Phenylalanine and Arginine

Answer 1

Histones are enriched with Lysine and Arginine.

Explanation:

Basic proteins called histones help wrap DNA into nucleosomes. Their high concentration of basic amino acids, particularly arginine and lysine, gives them a positive charge that enables them to bind tightly to negatively charged DNA (due to phosphate groups).
