Eukaryotic Chromosomes are composed of DNA, Histone and Nonhistone Proteins Histones: H1 H2A. H2 B, H3, H4. The later 4 form nucleosomes(100 A)and thus called core histones. H1 plays a role in forming 300 A superhelix Histones are rich in basic amino acids Nonhistone proteins play a variety of functions
