DNA Fingerprinting (RFLP Analysis)
In RFLP analysis, the DNA of an organism is cut up into fragments using restriction enzymes. A large number of short fragments of DNA will be produced.

VNTR's are used in DNA fingerprinting.
PCR has supplanted RFLP by Southern blotting and hybridization in analysis of VNTR's.
Simple sequence repeats can be used as genetic markers.
Details on many VNTR markers used by the US FBI are available.
