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 .
1952: an X-ray diffraction image of DNA was taken by Raymond Gosling in May 1952, a student supervised by Rosalind Franklin. [30] 1953: DNA structure is resolved to be a double helix by James Watson, Francis Crick and Maurice Wilkins. [31] 1955: Alexander R. Todd determined the chemical makeup of nitrogenous bases.
Alec Jeffreys. After finishing his doctorate, he moved to the University of Amsterdam, where he worked on mammalian genes as a research fellow, [15] and then to the University of Leicester in 1977, where in 1984 he discovered a method of showing variations between individuals' DNA, inventing and developing genetic fingerprinting.
The application of the new scanning Kelvin probe (SKP) fingerprinting technique, which makes no physical contact with the fingerprint and does not require the use of developers, has the potential to allow fingerprints to be recorded while still leaving intact material that could subsequently be subjected to DNA analysis.
By 1989 Alec Jeffreys, who had earlier developed and applied the first DNA Fingerprinting tests, used PCR to increase their sensitivity. [29] With further modification, the amplification of highly polymorphic Variable number tandem repeat (VNTR) loci became the standard protocol for National DNA Databases such as Combined DNA Index System (CODIS).
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.

The creation of a national DNA database within the U.S. was first mentioned by the Technical Working Group on DNA Analysis Methods (TWGDAM) in 1989. [1] The FBI's strategic goal was to maximize the voluntary participation of states and avoid what happened several years early, when eight western states frustrated with the progress creating a national Automated Fingerprint Identification System ...
