In this process, a gel matrix, often made of agarose or polyacrylamide, is prepared and loaded into a gel tray. The DNA fragments obtained from the restriction digestion are separated based on their size using a technique called gel electrophoresis. The choice of restriction enzymes depends on the target DNA sequence and the desired outcome of the analysis. These enzymes recognize specific DNA sequences, known as restriction sites, and cleave the DNA at or near these sites. The extracted DNA is treated with specific restriction enzymes (also known as restriction endonucleases). This typically involves breaking open the cells and isolating the DNA using specialized extraction protocols. DNA Extraction:ĭNA is extracted from the cells of the organism or sample of interest. Here is a step-by-step explanation of how RFLP analysis works: 1. RFLP analysis involves several key steps to analyze and compare variations in DNA sequences. As a consequence of this cleavage, the resulting DNA fragments exhibit variations in size, generating a distinctive fragment pattern that is unique to each individual or species. These enzymes have the capability to identify particular DNA sequences, referred to as restriction sites, and cleave the DNA at or in close proximity to these sites. The fundamental principle of Restriction Fragment Length Polymorphism (RFLP) is founded on the ability of specific enzymes called restriction enzymes or restriction endonucleases to divide DNA molecules into smaller fragments. Nonetheless, RFLP remains an essential tool in genetic research due to its historical significance and ability to provide valuable genetic insights. However, it has been largely surpassed by more advanced DNA sequencing methods. RFLP has been extensively applied in genetic mapping, exploring genetic diversity, and forensic identification. These variations in fragment sizes, referred to as polymorphisms, provide valuable information about genetic distinctions among individuals or species. Gel electrophoresis is then used to separate the DNA fragments, enabling their visualization and analysis. These enzymes identify and cut DNA at specific sites called restriction sites, generating smaller fragments. Restriction Fragment Length Polymorphism (RFLP) is a molecular biology technique that examines DNA sequence variations using specific enzymes known as restriction enzymes.
