WebHistone Octamer Structure. The structure of the octameric histone core of nucleosomes was observed under X-ray crystallography to a 3.1 A resolution. This histone octamer is a tripartite assembly wherein a tetramer is centrally placed and flanked by dimers – H2A-H2B. Their DNA is retained by ionic bonds. The linked histone HI associates with ... WebHistones H2A, H2B, H3, and H4 are known as the core histones, and histones H1 and H5 are known as the linker histones. The core histones all exist as dimers, and the four dimers come together to form one octameric nucleosome core. The smallest unit of chromatin structure is the nucleosome, consisting of 147 bp of DNA double helix wrapped around ...
