CODIS (Combined DNA Index System)

CODIS, or the Combined DNA Index System, is a national database used in the United States that stores DNA profiles from crime scenes and convicted offenders. It helps law enforcement agencies quickly match DNA evidence collected during investigations with profiles stored in the system. By facilitating comparison of genetic information, CODIS assists in solving crimes, identifying suspects, and exonerating innocent individuals. The system is operated by the FBI and plays a crucial role in criminal justice, enhancing both public safety and scientific accuracy in forensic investigations.
