DNA profiling (also called DNA fingerprinting and genetic fingerprinting) is the process of determining an individual's deoxyribonucleic acid characteristics. DNA analysis intended to identify a species, rather than an individual, is called DNA barcoding .
Baker realizes the usual routes of enquiry just aren’t working and comes to believe DNA fingerprinting holds more promise. He proposes to Jeffreys a plan to test every man in the area between ages 18 and 34, seeking a match to the killer’s DNA profile now in evidence. Jeffreys cautiously agrees with the plan in principle.
As with fingerprints, an individual's DNA profile and characteristics are unique. [citation needed] Forensic identification using DNA can be useful in different cases such as determining suspects in violent crimes, solving paternity/maternity, and identifying human remains of victims from mass disasters or missing person cases.

The first application of DNA profiles was used by Jeffreys in a double murder mystery in the small English town of Narborough, Leicestershire, in 1985. A 15-year-old school girl by the name of Lynda Mann was raped and murdered in Carlton Hayes psychiatric hospital. The police did not find a suspect but were able to obtain a semen sample.
"Children of color, families of color, have a smaller footprint in the DNA databases," Bischoff said. Bischoff said there is one tool that can be invaluable in helping identify these children.
Forensic biology is the application of biological principles and techniques in the investigation of criminal and civil cases. [1] [2]Forensic biology is primarily concerned with analyzing biological and serological evidence in order to obtain a DNA profile, which aids law enforcement in the identification of potential suspects or unidentified remains.

Rapid DNA is a "swab in-profile out" technology that completely automates the entire DNA extraction, amplification, and analysis process. Rapid DNA instruments are able to go from a swab to a DNA profile in as little as 90 minutes and eliminates the need for trained scientists to perform the process.
