(D) Histones are positively charged,basic proteins that are associated with $DNA$ in eukaryotic cells. They are rich in the basic amino acids $Lysine$ and $Arginine$. These amino acids carry positive charges in their side chains,which allow them to interact strongly with the negatively charged phosphate backbone of the $DNA$ molecule. Therefore,the correct option is $D$.
