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.
OK, so what DNA fingerprinting does is it looks for differences in the DNA that change where these restriction enzymes can cut DNA. The pattern of DNA fragments is then compared and if the child's DNA looks like a combination of the two parents' DNA, then the child is theirs.
