Polymerase chain reaction (PCR) enables researchers to produce billions of copies of a specific DNA sequence and is a featured technique in several DNALC-developed laboratory protocols. Participants in our field trips, camps, and workshops have been doing PCR experiments since 1995!
Polymerase Chain Reaction (Interactive): Click through this animation to follow PCR amplification step-by-step. Then look at the amplification graph to see how many DNA molecules are produced after 30 cycles of PCR.
