Histones F2al extracted from normal and neoplastic cells possess similar amino acid compositions. Tryptic and chymotryptic peptides of the F2al histones have identical chromato-electrophoretic R(F) values. It is concluded that histones F2al from various sources have similar overall structures. The observed differences in the ratios of in-N-monomethyl- and di-in-N-methyl-lysine in the histones from normal and neoplastic cells may be of significance with respect to gene regulation.
