WebbHistones are basic proteins found in chromosomes. They help in packing and organisation of DNA helix in chromatin fibre in the nucleus. They also regulate gene expression. In … WebbWhen DNA is wrapped around histones, the genes cannot be transcribed into RNA (and, eventually in protein). So these enzymes come along called HATs, which chemically modify the histones in effect loosening their grip on the DNA. This allows the transcriptional machinery access to the DNA, creating RNA (and, eventually, protein).
