From Wikipedia, the free encyclopedia. Short tandem repeat analysis (STR) is a molecular biology method used to compare specific loci on DNA from two or more samples.A short tandem repeat is a microsatellite, consisting of a unit of two to thirteen nucleotides repeated hundreds of times in a row on the DNA strand.STR analysis measures the exact number of repeating units. short tandem repeat is a microsatellite, consisting of a unit of two to thirteen nucleotides repeated hundreds of times in a row on the DNA strand. STR analysis measures the exact number of repeating units.
To perform a forensic DNA analysis, DNA is first extracted from a sample. Just one nanogram of DNA is usually a sufficient quantity to provide good data. The region containing each STR is then PCR amplified and resolved according to size, giving an overall profile of STR sizes (alleles).
