'''Histones''' (H) are the major protein components of chromatin which help to pack the DNA in the nucleosomes. H2A, H2B, H3 and H4 are core histones while H1 and H5 are linker histones<ref>PMID:16209651</ref>. 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<ref>PMID:4825889</ref>. 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.<br /> | '''Histones''' (H) are the major protein components of chromatin which help to pack the DNA in the nucleosomes.
