The Polymerase Chain Reaction (PCR) and the Future of Molecular Archaeology.
The Polymerase Chain Reaction (PCR) allows scientists to directly and exponentially amplify small samples of DNA. It will permit molecular archaeologists to analyze the genealogical relationships of extinct species and vanished populations and their relationship to living creatures. This paper outlines the technique and assesses its strengths and weaknesses. 7 pgs. 5 f/c. 6b.
