histones
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.
