Web1. Basic histone biology. Histones 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 [Citation 1].The histone … WebThe DNA- histone association is illustrated diagrammatically in Fig. 3.54. The nucleosome consists of approximately equal masses of DNA and histones. Histones neutralize a large portion of the phosphate groups of DNA. Histones make the DNA heat stable and protect it from radiation damage. Lysine-rich histones repress DNA from transcription.
