Proteins that are physically associated with DNA and are largely responsible for the structural organization of chromosomes.
(Greek, histos = web) One of a set of small, positively charged proteins that bind to DNA in eukaryotic cells. (More? DNA Notes)
A family of small, highly conserved basic proteins, found in the chromatin of all eukaryotic cells, that associate with DNA in the nucleosome.
nuclear proteins that coil DNA molecules.
proteins attached to the DNA of eukaryotes which allows it to be packaged into chromosomes.
Basic proteins that are involved in the packing of DNA. They bind to the phosphate groups of DNA. There are five major types of histone proteins.
Proteins that bind DNA and help wrap it into tightly packaged chromatin. Histones and other DNA-binding proteins can affect the pattern of gene expression in different cell types by controlling access to the DNA.
Highly basic proteins which associate with the chromosomal DNA to package it into a compact, higher order structure.
Proteins found in all eukaryotic nuclei which form complexes with DNA called "nucleosomes".
Small proteins with a high frequency of the basic and positively charged amino acids lysiine and arginine. The histone's strong positive charge enables them to bind and to neutralise the negatively charged DNA throughout the chromatin.
Basic proteins that are found associated with DNA in the chromatin fiber.
small, basic proteins that bind DNA to form the nucleosome.
a family of basic proteins found tightly associated with DNA in all eukaryotic nuclei; their binding forms a bead structure called a nucleosome. Return to text.
are simple proteins used to package the massive length of DNA in the relatively tiny cell nucleus.
Proteins associated with the DNA of the nucleus; the DNA strands are wound around them.
Proteins that play a part in the regulation of gene transcription by helping to condense DNA into its compact form as chromosomes.
