The DNA Analysis Unit I analyzes body fluids and body fluid stains recovered as evidence in violent crimes. Examinations include the identification and characterization of blood, semen, saliva, and other body fluids using traditional serological techniques and related biochemical analysis. Once the stain is identified, it is characterized by DNA analysis using the restriction fragment length polymorphism (RFLP) and/or polymerase chain reaction (PCR) techniques. The results of the analyses are compared to results obtained from known blood and/or saliva samples submitted from the victims and/or suspects.
