DNA Fingerprinting Using Minisatellite DNA - In this technique, DNA will be isolated from blood stains, semen stains or hair roots and will be subjected to Southern blotting and DNA hybridization with the help of specific DNA probes.

The probes correspond to hypervariable minisatellites in DNA, each made up of tendem rapeats of short sequences. A large number of these minisatellites are scattered throughout the human genome which were first detected in an intron of human/ myoglobin gene.

This will reveal polymorphism in DNA, which has a very stable inheritance.It is speculated that the above technique will allow the identification of criminals in murder cases, rapists in rape cases and of mother and or father in case of doubtful parentage.
