RFLP

In molecular biology, the term restriction fragment length polymorphism (or RFLP, often pronounced "rif-lip") is used in two related contexts: as a characteristic of DNA molecules (arising from their differing nucleotide sequences) by which they may be distinguished and as the laboratory technique which uses this characteristic to compare DNA molecules. The technique is utilized in genetic fingerprinting and paternity testing.

A difference in DNA between people that can be recognized by the use of a restriction enzyme.

(restriction fragment length polymorphism): Genetic polymorphism as revealed by the sizes of fragments generated with a particular restriction endonuclease enzyme (such as EcoRI, PstI, BglII).
