What is a key function of the Combined DNA Index System (CODIS)?

Supporting the collection of physical evidence
Facilitating DNA databases for criminal justice
Controlling evidence contamination
Documenting the chain of custody

The correct answer is: Facilitating DNA databases for criminal justice

The Combined DNA Index System (CODIS) serves as a vital tool in the realm of criminal justice by facilitating DNA databases. Its primary function is to store and compare DNA profiles obtained from crime scenes, suspects, and convicted offenders. By doing so, CODIS enables law enforcement agencies to connect crimes with known offenders or link cases that may otherwise appear unrelated. The system aids in solving cold cases and helps to identify repeat offenders, contributing significantly to public safety and the efficacy of the criminal justice system. This choice captures the essence of CODIS, emphasizing its role in maintaining a comprehensive database that supports investigations and enhances the collection and analysis of DNA evidence across jurisdictions. The effectiveness of CODIS relies on its ability to harmonize various DNA data across different law enforcement agencies and streamline the process of linking evidence to known individuals.
