a type of protein that plays a structural role in the packaging of DNA into nucleosomes, fundamental units of chromatin

- Nucleosomes, composed of histone proteins and DNA, are the basic repeating units of chromatin.

- The modification of histones can influence gene expression by regulating DNA accessibility.
- Changes in histone structure can influence the three-dimensional organization of the genome.
