Nucleosome
A nucleosome consists of a molecule of DNA wrapped around a core of eight histone proteins (an octamer)
- The negatively charged DNA associates with positively charged amino acids on the surface of the histone proteins
- The histone proteins have N-terminal tails which extrude outwards from the nucleosome
- During chromosomal condensation, tails from adjacent histone octamers link up and draw the nucleosomes closer together
