PCR stands for Polymerase Chain Reaction, which is a widely used laboratory technique for amplifying specific DNA sequences. It involves the use of a heat-stable DNA polymerase enzyme, primers (short pieces of DNA that match the target sequence), nucleotides (the building blocks of DNA), and a template DNA sample containing the target sequence.

The PCR technique is carried out through a series of temperature cycles that involve three basic steps: denaturation,
