Question 1: In the nucleus of eukaryotes, chromosomal DNA is packaged into nucleosomes, repeating units of DNA wound around conserved proteins called histones. Two of the histones that mammals produce are H3a and H3b, which differ only slightly in amino acid sequence and are encoded by separate, unlinked genes. H3a and H3b function during particular points in the cell cycle.
