DNA Fingerprinting (RFLP Analysis) Introduction DNA fingerprinting
... 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. Restriction enzymes always cut at the same base sequence. Because no two individuals have identical DNA, no two individuals will have the same lengt ...
