WebThe histoni su osnovni proteini koji u interakciji s DNK stvaraju nukleosome, koji čine hromatinske niti koje čine hromozome u eukariotskim organizmima. Nukleosomi, kompleksi koji se sastoje od DNK i proteina, otkriveni su 1974. godine i histoni su ti koji sastavljaju ovaj bazalni nivo organizacije hromatina. Međutim, postojanje proteina ...

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 … See more Five major families of histones exist: H1/H5, H2A, H2B, H3, and H4. Histones H2A, H2B, H3 and H4 are known as the core histones, while histones H1/H5 are known as the linker histones. The core histones … See more Compacting DNA strands Histones act as spools around which DNA winds.
