Basic

Vedclass · Answer

(B) Histone proteins are a group of proteins that are rich in basic amino acids,specifically $Lysine$ and $Arginine$.These amino acids carry positive charges in their side chains at physiological $pH$.Because $DNA$ is negatively charged due to the phosphate groups in its backbone,the positively charged histone proteins facilitate the packaging of $DNA$ into structural units called nucleosomes.Therefore,histone proteins are basic in nature.
