Introduction:
The DNA fingerprint or genetic fingerprinting is the process of analysing VNTR samples of DNA obtained from body fluids or cells so as to establish identity and relation of person. It was a chance discovery by alex jaffrey who was trying to visually identity DNA found between genes in the hope of finding some marker for inherited disease which could lead to their early treatment. In 1985 Jeffrey founded DNA of each individual has some non-cistronic hyper -variable repeat mini satellite f
sequences. This repeat many satellite sequence flanked by conserve restriction site are now commonly called VNTRs or variable number of tandem repeats. DNA fingerprinting is highly reliable method of identification of individuals involve in rape murder and other crimes.
