PCR Instructional Videos

The invention of the Polymerase Chain Reaction (PCR) radically changed biology.

Thanks to this technique, very small samples of DNA (from as little as a single cell) can be analyzed. PCR works by making billions of copies of DNA in just a few hours. PCR is now routinely used in forensic investigations, infectious disease testing and screening for genetic disease.
