In molecular biology, restriction fragment length polymorphism, or RFLP, is a technique that exploits variations in homologous DNA sequences. It refers to a difference between samples of homologous DNA molecules from differing locations of restriction enzyme sites, and to a related laboratory technique by which these segments can be illustrated. In RFLP analysis, the DNA sample is broken into pieces and (digested) by restriction enzymes and the resulting restriction fragments are separated according to their lengths by gel electrophoresis. Although now largely obsolete due to the rise of inexpensive DNA sequencing technologies, RFLP analysis was the first DNA profiling technique inexpensive enough to see widespread application. RFLP analysis was an important tool in genome mapping, localization of genes for genetic disorders, determination of risk for disease, and paternity testing.
Usage examples of "restriction fragment length polymorphism".
A restriction fragment length polymorphism DNA test could eliminate virtually any possibility that the blood had come from anyone else.
We have recently developed and refined a subset of DNA testing called RFLPS, which stands for restriction fragment length polymorphism.
