Restriction Fragment Length Polymorphism Analysis

Overview

Restriction fragment length polymorphism (RFLP) analysis is a molecular biology technique used to detect genetic variation between individuals, populations, or species by examining differences in the lengths of DNA fragments produced when DNA is cut by restriction enzymes. These enzymes recognize and cut at specific short sequences, so variations in the DNA sequence among samples alter the number and positions of cut sites, yielding fragments of differing lengths that can be separated by size and compared. RFLP analysis has been used for genetic mapping, identifying disease-associated variants, distinguishing strains of organisms, paternity and forensic testing, and studying evolutionary relationships, and although newer sequencing methods have largely superseded it, it remains a foundational concept in genetics. As a journal of Digestive Disorders And Diagnosis, this title's scope centers on gastrointestinal disease and its diagnosis, contexts in which genetic and molecular methods can support investigation. The articles associated with this page address genetic polymorphisms in epilepsy and proteomic and genomic techniques in medical research rather than RFLP analysis specifically, so this entry provides an encyclopedic definition within the journal's diagnostic scope. It serves as a reference overview of RFLP analysis and its role in detecting genetic variation.
