Histones are enriched with -

Options

  1. ALysine & Arginine
  2. BLeucine & Lysine
  3. CPhenylalanine & Leucine
  4. DPhenylalanine & Arginine

Correct answer

A. Lysine & Arginine

Step-by-step solution

In eukaryotes, packaging of DNA is much more complex. There is a set of positively charged, basic proteins called histones. Histones are organised to form a unit of light molecules called histone octamer. They are rich in the basic amino acid residues lysine and arginine.
