10108360072Forensic ScienceThe application of science to law. The application of science to those criminal and civil laws that are enforced by police agencies in a criminal justice system. The focus of forensics is the crime lab. The crime lab uses the principles and technique of biology, chemistry, physics, geology, anthropology, and other sciences in order to place physical evidence into a professional discipline.7

10108360112CODISCombined DNA Index System (FBI). Used to share DNA profiles kept in the FBI's National DNA Index System (NDIS) with law enforcement bodies.31
