What will be an ideal response?
PCR (polymerase chain reaction) is a technique for replicating or copying a portion of a DNA strand outside a living cell. Three advantages of PCR are that (1) PCR can be used with short DNA strands, (2) shorter strands are more stable and less subject to degradation than longer strands, and (3) PCR can amplify minute quantities of DNA, thus overcoming the limited-sample-size problem often associated with crime-scene evidence.
