H2A, H2B, H3 and H4 are core histones while H1 and H5 are linker histones. The nucleosome is the repeated unit of the chromatin consisting of a core which contains 8 histone molecules (two copies of H2A, H2B, H3 and H4) wrapped by ca. 140 base pairs of DNA. The chromatin is made of nucleosome cores separated by a linker region of upto 80 base pairs of DNA associated with histones H1 and H5. For the hyperthermophilic histones see Archaeal Histones. For nucleosome structure see User:Eric Martz/Nucleosomes, Nucleosome structure and Nucleosomes.
