WebMar 29, 2024 · Histones are basic nuclear proteins that are responsible for the nucleosome structure of the chromosomal fiber in eukaryotes. Two molecules of each of the four core histones (H2A, H2B, H3, and H4) form an octamer, around which approximately 146 bp of DNA is wrapped in repeating units, called nucleosomes. WebHistones are basic proteins that provide a scaffold to wrap and condense DNA in the nucleus. The binding of histones to DNA is altered by acetylation or deacetylation of histone lysine residues, which determines the accessibility of the regulatory regions of genes to transcription factors facilitating transcription.
