"WebbHistone acetylation involves the covalent addition of an acetyl group to lysine (Fig. 5.11).Because of its –NH 2 group, lysine is normally a positively charged amino acid, which binds strongly to the negatively charged DNA molecule. The addition of the acetyl group neutralizes this positive charge and hence reduces the binding between histones and … " - Histone chromatin
