Chromatin structure, diagram. The main artwork shows various molecules and a strand of DNA (deoxyribonucleic acid, red) looping round a cylindrical histone core (blue), forming a structure known as a nucleosome. The yellow region is a section of cytosine-guanine (labelled CpG-GpC) di-nucleotides that play a role in chromatin formation. Also shown here is acetylation, deacetylation, methylation, and demethylation. Strings of nucleosomes (lower left) form the structure called 'beads on a string'. Further compacting (lower right) condenses the chromatin even more to fit inside cell nuclei.
