What does the acronym CODIS stand for in relation to DNA databases?

The acronym CODIS stands for Combined DNA Index System. This national database facilitates the sharing and comparison of DNA profiles collected from crime scenes, offenders, and missing persons across multiple jurisdictions. CODIS allows forensic scientists to match DNA from evidence with DNA profiles already in the database, thereby helping to solve crimes and identify individuals involved in criminal activity.

The purpose of the system is to enable law enforcement agencies to access a larger pool of DNA profiles, which increases the chances of finding matches that could lead to solving cases. The CODIS system operates at various levels, including local, state, and national databases, ensuring a comprehensive approach to DNA evidence management.

The other options presented, while they may seem plausible, do not accurately reflect the established terminology used within forensic science for the DNA indexing system.
