PCR/STR Analysis

Close up of PCR tube

Short Tandem Repeat (STR) Analysis is a relatively new technology in the area of forensic science. It has been notably identified as “genetic fingerprinting.” Results from this analysis are most often used in the identification of a suspect in a crime. These results are input into the Combined DNA Index System (CODIS) for matching purposes. CODIS is an FBI-funded computer database, which stores the DNA of convicted sex offenders, convicted murderers, certain felony offenders and other criminals.
