Federal Bureau of Investigation DNA Analysis Units
Federal Bureau of Investigation DNA Analysis Units (Forensic Science)
The Federal Bureau of Investigation (FBI) operates one of the world’s largest forensic laboratories. The FBI Laboratory, commonly referred to as the FBI crime lab, comprises branches and sections that are further divided into special units. In 1988, the DNA Unit was established as part of the lab’s Scientific Analysis Section. The new unit included biologists, forensic examiners, specialists in DNA (deoxyribonucleic acid) analysis, and management and program analysts. In 1998, the DNA Unit was divided into two more specialized units: the DNA Analysis Unit I (DNAAU-1) and the DNA Analysis Unit II (DNAAU-2).
DNAAU-1 examines evidence from a variety of crimes and provides serological and nuclear DNA testing services. Serological techniques assist in DNA analysis by identifying whether biological stains are blood, semen, or other body fluids. DNA samples may also be obtained from a variety of other sources, such as saliva left on cigarette butts, envelopes, or beverage bottles and from sweat deposited inside hats. Nuclear DNA testing is performed on the evidence, and the findings are compared with the DNA found in reference samples obtained from crime victims or suspects.
In accordance with the Federal Convicted offender Program, DNAAU-1 also conducts DNA analysis on all individuals convicted of federal felonies. The resulting DNA profiles are entered into the National DNA Index System (NDIS). Additionally, DNAAU-1 offers...
