the sequence. They are surrounded by nonvariable segments of DNA known as flanking regions. For example, the STR allele in Figure 1 could be designated as “6” because the repeat unit (GATA) repeats six times, or as 70 bp (where bp stands for base pairs) because it is 70 bp in length, including the flanking regions. A

The standard polymerase chain reaction (PCR) is used to amplify a segment of DNA that lies between two inward-pointing primers.
