H2a histone function
WebHistones are divided into two main categories, linker histones (H1 and H5) and core histones (H2A, H2B, H3, and H4). While histones play an important role in DNA packaging, where DNA is wrapped around histones, they are also involved in several other functions that include: Shaping the chromosomes Regulate gene activities Chromatic regulation WebIn humans and other eukaryotes, the DNA is wrapped around histone octamers, consisting of core histones H2A, H2B, H3 and H4, to form chromatin. H2AX contributes to …
