IB PCR Virtual Lab
The development of Polymerase Chain Reaction (PCR) in 1983 by Kary Mullis resulted in the a nobel prize for the inventor and a means to create thousands to millions of copies of a single region of DNA. This process is now used in DNA cloning, fingerprinting, analysis of genes, DNA phylogeny, and other areas of science.
