Vedclass · Answer

(D) Histones are a group of positively charged,basic proteins that are associated with $DNA$ in the chromatin of eukaryotic cells.They are rich in the basic amino acids $Lysine$ and $Arginine$.These amino acids carry positive charges in their side chains at physiological $pH$,which allows the histones to bind tightly to the negatively charged phosphate backbone of the $DNA$ molecule.
