<p>test. Microsatellite regions are usually characterized by short, repeated sequences of nucleotides. <a href="page.php?w=Primer_%28molecular_biology%29">Primer</a>s that are specific to a particular locus are used in PCR amplification to bind to these nucleotide sequence repeats and are used as genetic markers. The primers anneal to either end of the locus and are derived from source organisms in a genomic library. Divergence from the reference sequences (from genetic mutations) results in poor annealing of the primers so that the marker cannot</p><p>
