histones

Histones are proteins that are critical in the packing of DNA into the cell and into chromatin and chromosomes. They're also very important for regulation of genes.

Histones are simple, water-soluble proteins attached to the DNA of eukaryotes which allows this DNA to be packaged into chromosomes. There are five varieties of histones, each containing a large proportion of the amino acids arginine, lysine, and histidine. They are involved in the condensation and coiling of chromosomes during cell division and have also been implicated in the nonspecific suppression of gene activity.
