What is DNA Fingerprinting? DNA fingerprinting is a process through which the unique genetic code of a person is identified and codified. DNA fingerprint is called so because just like the technology of fingerprint became very popular in the 1930s as means of crime detection, beginning in the 80s, DNA testing achieved a similar level of popularity in forensic science.
DNA fingerprinting was invented in 1984 by Professor Sir Alec Jeffreys after he realised you could detect variations in human DNA, in the form of these minisatellites. DNA fingerprinting is a technique that simultaneously detects lots of minisatellites in the genome to produce a pattern unique to an individual. This is a DNA fingerprint. The probability of having two people with the same DNA fingerprint that are not identical twins is very small. Just like your actual fingerprint, your DNA fingerprint is something you are born with, it is unique to you. The first step of DNA fingerprinting was to extract DNA from a sample of human material, usually blood.
