In chromatin, DNA winds around disc-shaped clusters of eight proteins called histones.

In the field of biology, chromatin can be described as a highly compact, condensed structure of DNA and the proteins called histones that form the chromosomes in organisms.

The charge of histone proteins is positive whereas the charge of DNA is negative, these opposite charges make it possible for the DNA to be wrapped by the histone proteins.

The chromatin and histones together form the nucleosome. In a nucleosome, the chromatin material is wrapped by eight histone proteins which are double copies of H2A, H2B, H3, and H4, referred to as the histone octamer. All the nucleosomes are then held in compact form by the H1 histone protein.
