DNA fingerprinting is a very quick way to compare the DNA sequences of any two living organisms. DNA fingerprinting is a laboratory procedure that requires six steps: 1: Isolation of DNA. DNA must be recovered from the cells or tissues of the body.Only a small amount of tissue-like blood, hair, or skin-is needed.pecial enzymes called restriction enzymes are used to cut the DNA at specific places. For example, an enzyme called EcoR1, found in bacteria, will cut DNA only when the sequence GAATTC occurs. The DNA pieces are sorted according to size by a sieving technique called electrophoresis.
