Restriction Fragment Length Polymorphism or RFLP is a method of genetic investigation on the molecular level that permits individuals to be recognized based on distinctive patterns of restriction enzyme cleave in specific points of DNA.
The basic technique for the identification of RFLPs involves segmenting a sample of DNA with the help of a restriction enzyme. Restriction enzymes can selectively restrict a DNA molecule wherever specific, short sequence is recognized.
Hence, RFLPs are referred to as DNA fingerprinting bands.
