Vedclass · Answer

(C) Histones are a group of basic proteins that are associated with $DNA$ in the chromatin of eukaryotic cells.They are rich in basic amino acid residues,specifically $Lysine$ and $Arginine$.Due to the presence of these basic amino acids,histones carry a positive charge at their side chains at physiological $pH$.This positive charge allows them to interact with the negatively charged phosphate backbone of the $DNA$ molecule to form nucleosomes.
