A protein around which DNA coils to form chromatin. Without histones, DNA could not organize into chromosomes.

A type of protein found in chromosomes. Histones bind to DNA, help give chromosomes their shape, and help control the activity of genes.

(hiss-tone) A small protein with a high proportion of positively charged amino acids that binds to the negatively charged DNA and plays a key role in its chromatin structure.

1885, from German histon (1884); see histo- + -one.

A histone is a protein that provides structural support to a chromosome. In order for very long DNA molecules to fit into the cell nucleus, they wrap around complexes of histone proteins, giving the chromosome a more compact shape. Some variants of histones are associated with the regulation of gene expression.

Any of five related proteins, composed primarily of basic amino acids, which are the scaffold around which DNA is wound to form the chromatin structure of eukaryotic chromosomes. 29 Animation, 29 Gall [..]

Any of several simple proteins found in cell nuclei and complexed at one time or another with DNA. Histones yield a high proportion of basic amino acids on hydrolysis; characteristic of eukaryotes. histozoic

A family of simple proteins, abundant in the cell nucleus and constituting a substantial part of the (mostly) protein/RNA

Small basic proteins that bind to DNA in chromatin.

(French : histone) Basic chromosomal proteins present in eukaryotes believed to be involved in the coiling and condensation of chromosomes.

(n) a simple protein containing mainly basic amino acids; present in cell nuclei in association with nucleic acids

protein that binds to DNA and packages it into compact structures to form nucleosomes.

Small chromosomal Proteins (approx 12-20 kD) possessing an open, unfolded structure and attached to the DNA in Cell Nuclei by ionic linkages. Classification into the various types (designated histone [..]

One of a class of basic proteins that are complexed with DNA

A type of protein found in chromosomes. Histones bind to DNA, help give chromosomes their shape, and help control the activity of genes.

An alkaline protein in the eukaryotic nucleus and a major component of chromatin. DNA coils around histones and in turn, histones play a role in gene expression.

Abundant small protein rich in arginine and lysine that associates with DNA and enables the packaging of DNA into chromosomes.

A type of basic protein that forms the unit around which DNA is coiled in the nucleosomes of eukaryotic chromosomes. Arginine and lysine rich basic proteins making up a substantial portion of eukaryot [..]

a type of protein molecule found in the chromosomes of eukaryotic cells but not prokaryotic cells
