NCIt definition : DNA that contains many tandem highly repetitive sequences, that have a base composition
(and thus density) sufficiently different from that of normal DNA that it sediments
as a distinct band in cesium chloride density gradients. 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 22, and near the centromeres of
chromosomes).;
