Answer to Question 1

Tandem repeats are regions of a chromosome that contain multiple copies of a core DNA sequence arranged in a repeating fashion. They are useful to forensic scientists because they offer a means of distinguishing one individual from another through DNA typing.

Answer to Question 2

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.
