Chromatin Each spool & its DNA is called a nucleosome the first level of DNA packing in eukaryotic chromatin. 3-29 Nucleosomes contain proteins called histones and these are responsible for the first level of DNA packing in eukaryotic chromatin Histones have high proportion of positively charged amino acids and they bind tightly to the negatively charged DNA.
