Isn't it amazing to find out a criminal just by examining a trace of his blood or a part of his hair with the evidence found on the crime site. Well, I know its not that easy but yes it is one of the most trusted tests done in the forensic science department. DNA fingerprinting techniques have created wonders from the time it has been invented. It is also known as DNA profiling, DNA testing, DNA typing and genetic fingerprint. Now the very obvious question is who invented DNA fingerprinting? An English geneticist, Dr. Alec J. Jeffreys invented this technique in the year 1984. He found that in the DNA there are DNA sequences which are repeated again and again and the number of repeated sequence is different in different people. By finding out the length of the DNA and the number of DNA sequences one can perform the identity test. Let's go through the detailed history of DNA fingerprinting and find some remarkable events.
