satellite DNA
satellite DNA Any DNA which differs enough in its base composition to form a separate fraction from the majority of genomic DNA on centrifugation. This bias in base composition is often due to highly repetitious DNA. Satellite DNA may consist of dispersed repeats (e.g.
long interdispersed elements and
short interdispersed elements) or may be arranged in a
tandem array. In a tandem array it may have very short repeating units, 2–10 base pairs in the case of microsatellite DNA, or slightly longer ones, 10–100 base pairs in the case of minisatellite DNA. The number of repeating units within a single satellite tandem array changes rapidly in evolutionary terms, due to the processes of
replication slippage and
unequal crossing over. Consequently, the length of an array can be used as a highly informative character in
phylogenetic analysis at the intraspecific level. By using many such arrays a highly specific set of
character states can be established, by which an individual organism may be identified; this is a DNA fingerprint.
