General Information
DNA fingerprinting or profiling is a technique that identifies the DNA from a certain individual without examining the entire three billion letters in the full human genome. It can be used to track down criminals, test the parentage of children, and to follow the evolution of species.
DNA fingerprinting allows a criminal to be identified from any blood, semen, or even hair or dead skin they may leave at the scene of the crime. A DNA fingerprint scans perticular DNA regions to create a DNA profile (a fingerprint) of the individual. This allows police to very quickly exclude or include a suspect in their investigation. The accuracy of DNA testing is of crucial importance in many legal cases. Although no two unrelated people have been found with the same fingerprint, this cannot be ruled out.
Additional methods utilized in criminal profiling include FBI-CODIS (Combined DNA Index System) sequence patterns, against which DNA profiles developed from crime scene evidence can be compared. FBI-CODIS contains a conivicted offender database of DNA profiles that forensic scientists utilize to discover matches in DNA profiles. Due to the recidivistic nature of crimes, often the DNA profile developed from crime scene evidence will be contained in a criminal database, that can be searched by the CODIS. See Forensic DNA Identification for more information on FBI-CODIS.
