What is "polymerase chain reaction"?
Polymerase chain reaction (PCR) is a lab technique used to make many copies of a specific part of DNA. It involves mixing a small sample of DNA with special chemicals and enzymes. These enzymes help copy the DNA by repeatedly heating and cooling the mixture. PCR makes it possible to turn a small amount of DNA into a large amount that can be tested. This technique is widely used in medical tests, research, and forensic science to identify infections, study genetic information, and analyze DNA sequences.
