The histones are evolutionarily conserved proteins that are rich in basic amino acids and form an octamer. The DNA (which is negatively charged because of the phosphate groups) is wrapped tightly around the histone core.
WebDNA packaging is mediated by histone proteins. The core nucleosome particle is composed of 147 bp of DNA wrapped around an octamer of four core histone proteins. These nucleosomes fold into 30 nm chromatin fibers, which are the components that make up a chromosome.
