| nucleosome | <cell biology> Repeating units of organisation of chromatin fibres in chromosomes, consisting of around 200 base pairs and two molecules each of the histones H2A, H2B, H3 and H4. most of the DNA (around 140 base pairs) is believed to be wound around a core formed by the histones, the remainder joins adjacent nucleosomes, thus forming a structure reminiscent of a string of beads. Origin: Gr. Soma = body (18 Nov 1997) |

| nucleosomes | The repeating structural units of chromatin, each consisting of approximately 200 base pairs of DNA wound around a protein core. This core is composed of the histones h2a, h2b, h3, and h4. (12 Dec 1998) |
Synonyms : Dinucleosomes, Polynucleosomes, Dinucleosome, Nucleosome, Polynucleosome
| nucleosome |
Spherical sub-units of eukaryotic chromatin that are composed of a core particle consisting of an octamer of histones (two molecules each of histones H 2a , H 2b , H 3 and H 4 ) and 146 nucleotide pairs.

| nucleosome |
The fundamental structural unit of eukaryotic chromosomes. It consists of pairs of each of the core histones (H2A, H2B, H3 and H4), thereby creating the histone octamer, and a single molecule of the linker histone H1. The nucleosome spans 180 base pairs of DNA. During apoptotic cell death, cleavage of nuclear DNA typically occurs at these nucleosomal intervals.
