• repetitive DNA — Nucleotide sequences in DNA that are present in the genome as numerous copies. Originally identified by the value on the Cot curve derived from kinetic studies of DNA renaturation. These sequences are not thought to code for polypeptides. One… …   Dictionary of molecular biology

• repetitive DNA — nucleotide sequences occurring multiply within a genome; they are characteristic of eukaryotes and generally do not encode polypeptides. Sequences may be clustered or dispersed, and repeated moderately (10 to 104 copies per genome) to highly… …   Medical dictionary

• Satellite DNA — DNA that contains many tandem (not inverted) repeats of a short basic repeating unit. Satellite DNA is located at very specific spots in the genome (on chromosomes 1, 9, 16 and the Y chromosome, the tiny short arms of chromosomes 13 15 and 21 and …   Medical dictionary

• satellite DNA — (= minisatellite; microsatellite) DNA, usually containing highly repetitive sequences, that has a base composition (and thus density) sufficiently different from that of normal DNA that it sediments as a distinct band in caesium chloride density… …   Dictionary of molecular biology
