How does the charge of a protein depend on its amino acid residues?

Step-by-step solution

In eukaryotes, this organization 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. Histones are organized to form a unit of eight molecules called histone octamer. The negatively charged DNA is wrapped around the positively ch
