Microsatellite DNA consists of short, repeating sequences of non-coding DNA. Because their mutation rate is relatively high and unique to lineages, they act as highly effective genetic markers. They are extensively used in population genetics, DNA profiling (fingerprinting), and studying evolutionary relationships and pedigree among different animal and plant species.
