New American Oxford Dictionary

chromosome

chro mo some |ˈkrōməˌsōm ˈkroʊməˌsoʊm | ▶noun Biology a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes. Each chromosome consists of a DNA double helix bearing a linear sequence of genes, coiled and recoiled around aggregated proteins (histones ). Their number varies from species to species: humans have 22 pairs plus the two sex chromosomes (two X chromosomes in females, one X and one Y in males ). During cell division, each DNA strand is duplicated, and the chromosomes condense to become visible as distinct pairs of chromatids joined at the centromere. Bacteria and viruses lack a nucleus and have a single chromosome without histones. DERIVATIVES chro mo so mal |ˌkrōməˈsōməl |adjective ORIGIN late 19th cent.: coined in German from Greek khrōma ‘color ’ + sōma ‘body. ’

 

chromosome map

chro mo some map ▶noun Genetics a diagram showing the relative positions of genes along the length of a chromosome.

 

chromosome number

chro mo some num ber ▶noun Genetics the characteristic number of chromosomes found in the cell nuclei of organisms of a particular species.
