Vedclass · Answer

(C) The correct answer is $C$. Histones are positively charged proteins because they contain a very high proportion of basic amino acids,specifically $Lysine$ and $Arginine$. These amino acids possess positively charged side chains at physiological $pH$. Because of this positive charge,histones can effectively bind to the negatively charged phosphate backbone of $DNA$ to form nucleosomes.

Histone proteins are positively charged because they are rich in basic amino acid residues:
