PCR

Polymerase Chain Reaction (PCR)- Principle, Steps, Applications PCR is an enzymatic process in which a specific region of DNA is replicated over and over again to yield many copies of a particular sequence. The most widely used target nucleic acid amplification method is the polymerase chain reaction (PCR). This method combines the principles of complementary nucleic acid hybridization with those …
