Polymerase chain reaction. Polymerase chain reaction, (PCR), a technique used to make numerous copies of a specific segment of DNA quickly and accurately.
Methods. A common procedure for DNA fingerprinting is restriction fragment length polymorphism (RFLP). In this method, DNA is extracted from a sample and cut into segments using special restriction enzymes.RFLP focuses on segments that contain sequences of repeated DNA bases, which vary widely from person to person.n this method, DNA is extracted from a sample and cut into segments using special restriction enzymes.
