Histone

In biology, histones are highly alkaline proteins found in eukaryotic cell nuclei that package and order the DNA into structural units called nucleosomes. They are the chief protein components of chromatin, acting as spools around which DNA winds, and play a role in gene regulation. Without histones, the unwound DNA in chromosomes would be very lo...

histone

<molecular biology> Protein found in the nuclei of all eukaryotic cells where they are complexed to DNA in chromatin and chromosomes. They are of relatively low molecular weight and are basic, having a very high arginine/lysine content. They are highly conserved and can be grouped into five major classes. Two copies of H2A, H2B, H3 and H4 bin...

histone

histone One of the five kinds of proteins that are part of chromatin in eukaryotic cells. Their positive charge attracts the negatively charged DNA that is folded around them into units called nucleosomes. Histones also regulate some of the further folding of DNA in chromosomes about to undergo mitosis.
