  • What Is the Purpose of Histones in DNA and Gene Regulation?
    Histones serve as the primary architectural components of chromatin, forming nucleosomes—the fundamental repeating units of chromatin Each nucleosome consists of an octamer of histone proteins, composed of two copies each of H2A, H2B, H3, and H4, around which 147 base pairs of DNA are wrapped

  • The secret life of histones | Science - AAAS
    Histone proteins are the ubiquitous organizers of all eukaryotic genomes Two each of the histones H2A, H2B, H3, and H4 form a disk-shaped assembly around which 147 base pairs (bp) of DNA are tightly coiled Hundreds of thousands of these connected nucleosomes wrap up further to form chromosomes
