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 | |
