What Is Forensic DNA Analysis?
Forensic DNA analysis is used to identify individuals using genetic samples. Basically, the system uses a set of identifying numbers to match two different samples. The concept was first designed by Sir Alec Jeffreys at the University of Leicester in 1985. Today, it is a standard practice in conducting investigations for crimes such as murder and rape.

The process of forensic DNA analysis begins with DNA samples from an individual. This can come from bodily fluids such as blood, saliva or semen. It is usually obtained from personal items or stored samples. A reference sample must be made from a number of techniques and compared to samples to determine a genetic match. This is most commonly conducted using a buccal swab, or cheek swab, in the mouth.
