The basic amino acid residues present in abundance in histones are:

The correct answer is Option (3) → Lysine and Arginine

Option (3) Lysine and Arginine — Correct. Of the options, only lysine and arginine are basic amino acids with positively charged side chains. This gives histones their positive charge, so they can hold the negatively charged DNA.

NCERT Extract:
Packaging of DNA Helix – “… In eukaryotes, this organisation is much more complex. There is a set of positively charged, basic proteins called histones. A protein acquires charge depending upon the abundance of amino acids residues with charged side chains. Histones are rich in the basic amino acid residues lysine and arginine. Both the amino acid residues carry positive charges in their side chains.”
