WebApr 9, 2024 · Histones are proteins that play an important role in the packing of DNA into cells, chromatin, and chromosomes. They are also crucial for gene regulation. We used to think of histones as sort of DNA suitcases that held the DNA, but it became clear that histones are regulated and have a lot to do with when genes are turned on and off. WebHistones are proteins that condense and structure the DNA of eukaryotic cell nuclei into units called nucleosomes. Their main functions are to compact DNA and regulate …
