WebbHistones are structural subunits that provide a core in which chromatin can be wrapped around. The core comprises of two H2A–H2B dimers and an (H3–H4) 2 tetramer (histone octamer) with an external H1 histone, a conserved subunit that assists with maintaining this ‘beads on a string’ structure ( Figure 1) [ 1 ].
