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 .
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.
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.

In the 1960s, accurate genetic paternity testing became a possibility when HLA typing was developed, which compares the genetic fingerprints on white blood cells between the child and alleged parent. [12] HLA tests could be done with 80% accuracy but could not distinguish between close relatives. [13]
A Fingerprint Bureau was established in Calcutta , India, in 1897, after the Council of the Governor General approved a committee report that fingerprints should be used for the classification of criminal records. Working in the Calcutta Anthropometric Bureau, before it became the Fingerprint Bureau, were Azizul Haque and Hem Chandra Bose.
Alec Jeffreys is known as the "founding father of DNA identification”. [11] He invented DNA fingerprinting in the 1980s to assist in the process of body identification. [11] Since then, the method of DNA typing in forensic science has advanced and many techniques to identify microRNA markers in bodily fluids have developed. [21]
DNA sequencing may be used along with DNA profiling methods for forensic identification [21] and paternity testing. DNA testing has evolved tremendously in the last few decades to ultimately link a DNA print to what is under investigation. The DNA patterns in fingerprint, saliva, hair follicles, etc. uniquely separate each living organism from ...
This process is formally termed DNA profiling, also called DNA fingerprinting. In DNA profiling, the lengths of variable sections of repetitive DNA, such as short tandem repeats and minisatellites, are compared between people. This method is usually an extremely reliable technique for identifying a matching DNA. [164]
