n.
1. A short sequence of DNA consisting of multiple repetitions of a set of two to nine base pairs, used as a genetic marker when individuals differ in the number of repetitions.
2. A small artificial satellite, usually with a mass of less than 100 kilograms (220 pounds) when deployed in orbit.

n
(Genetics) genetics a section of DNA consisting of very short nucleotide sequences repeated many times, the number of repeats varying between members of the species: used as a marker in determining genetic diversity, identifying important genetic traits, and in forensics, population studies, and paternity studies

Geneticists and biologists from Europe, the US, and Brazil describe the repetitive content of eukaryotic genomes and the impact on genome structure, function, and evolution; the birth-and-death model as the mechanism guiding long-term evolution of multigene families; centromeres; telomere metabolism and its dynamics, with an emphasis on human biology; Drosophilia telomeres; satellite-DNA mediated effects on genome regulation; the evolutionary dynamics of transposable elements in eukaryotic genomes; short interspersed elements (SINEs) in genome evolution; unstable microsatellite repeats in the rapid evolution of coding and regulatory sequences; and chromosomal distribution and evolution of repetitive DNA in fish.
