Polymerase chain reaction (PCR) is a fundamental molecular biology tool that scientists use to amplify and analyze genetic material, such as DNA and RNA. PCR involves the enzymatic amplification of ...

First developed more than four decades ago as a biological research technique to amplify nucleic acids, polymerase chain reaction (PCR) technology still has untapped potential, with many exciting ...

In 2003, Kary Mullis took The Scientist readers behind the scenes of the night in 1983 when he came up with the idea for PCR. He included a photo of his lab notebook that depicts his very first ...

The COVID-19 pandemic led to many changes. Among them is universal familiarity with a molecular diagnostic technique that was largely unknown outside clinical use. The polymerase chain reaction — or ...
