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 chromatin, therefore impacting gene regulation. List the 4 core histones. Histones H2A, H2B, H3 and H4 are known as the core histones, and they come together to form one nucleosome. Webhistone a type of simple protein that is usually basic and tends to form complexes with nucleic acids (e.g. DNA) forming NUCLEOSOMES.
