A computerized database that allows an analyst to obtain information relative to an individual's DNA profile is :

  • A.PCR
  • B.CODIS
  • C.AFIS
  • D.PDQ

Answer: B

The DNA profile database is CODIS.

CODIS, the Combined DNA Index System, is the FBI's software and database linking DNA profiles at local, state and national levels. An analyst searches a profile from a crime scene against the indexes of offenders, arrestees and forensic unknowns to find a match.

PCR, the polymerase chain reaction, is the technique that copies DNA, not a database. AFIS is the fingerprint database, and PDQ (Paint Data Query) is the RCMP's database of automotive paint.
