RESTRICTION FRAGMENT LENGTH POLYMORPHISMS (RFLPs): Differences in DNA sequence on homologous chromosomes that can result in different patterns of restriction fragment lengths (DNA segments resulting from treatment with restriction enzymes).
This week on AZPI: Forensic DNA - Two different DNA tests exist, the RFLP and the PCR. Both are very accurate, but they’re conducted in different ways. The restriction fragment length polymorphism or RFLP (sometimes called DNA fingerprinting or profiling) is considered to be the more accurate of the two.
* PCR tubes - The polymerase chain reaction (PCR) is a technology in molecular biology used to amplify a single copy or a few copies of a piece of DNA across several orders of magnitude, generating thousands to millions of copies of a particular DNA sequence.
