Polymerase Chain Reaction

Today in lab, we did polymerase chain reaction to amplify a specific section of our own DNA. We did two PCRs. We amplified DNA sequences that may vary from person to person. People can use PCR to amplify small amount of DNA and determine who the owner of the DNA is. It is useful in solving crimes and detecting diseases. According to Jody, PCR is the most important technique of biotechnology in the twentieth century. Although PCR is essentially just a technique to amplify DNA, by changing the primers of PCR, one can accomplish a lot more things than just making DNA.
