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. … screwfix stoke on trent st4 8grWebOct 11, 2024 · histone: [noun] any of various simple water-soluble proteins that are rich in the basic amino acids lysine and arginine and are complexed with DNA in the … screwfix stone sealerWebHristina diligently followed all requisite steps, proving that she is a person who gets things done once she has set her mind.
