Histone - an overview ScienceDirect Topics

In biology, histones are highly basic proteins abundant in lysine and arginine residues that are found in eukaryotic cell nuclei. They act as spools around which DNA winds to create structural units called nucleosomes. Nucleosomes in turn are wrapped into 30-nanometer fibers that form tightly packed chromatin. Histones prevent DNA from becoming tangled and protect it from DNA damage. … WebJan 29, 2016 · Histones belong to a family of highly basic proteins whose primary job is to associate with DNA and condense the chromatin.

It consists of two copies of each of the four core histone proteins ( H2A, H2B, H3, and H4 ). The octamer assembles when a tetramer, containing two copies of H3 and two of H4, complexes with two H2A/H2B dimers. crude birth rate vs tfr
