Biology / DNA
Examiners in the Forensic Biology specialty routinely examine items of evidence for the presence of blood and seminal fluid. After the proper samples for comparison are obtained, DNA analysis can be conducted on these stains, and conclusions drawn as to whether an individual can be eliminated or included as a possible contributor to the genetic material identified. When the DNA database is completed, the DNA profile obtained from an unidentified assailant will be compared to the profiles in the database of convicted offenders for a possible match.
