Q&A

• How did Kary Mullis contribute to science despite controversies?

  Kary Mullis, the Nobel Prize winner in chemistry, made significant contributions to science with the invention of PCR, which later became crucial in COVID testing, despite his eccentric behavior and controversial activities.

• What controversies surrounded the discovery of PCR?

  The discovery of Taq polymerase led to a patent struggle and controversy over credit for PCR. Kary Mullis, the inventor, claimed sole credit, causing widespread controversy.

• What challenges did the development of PCR face?

  The development of PCR faced skepticism and challenges but eventually succeeded, with the discovery of Taq polymerase providing a solution to the high-temperature requirements of the process.

• How did Kary Mullis come up with the idea for PCR?

  Mullis visualized DNA chains and came up with the idea of using primers, polymerase, and DNA replication to create billions of copies of a specific DNA segment, eventually naming the process polymerase chain reaction (PCR).

• How did scientists separate and detect DNA mutations before PCR?

  Scientists used gel electrophoresis to separate DNA by length and used specific probes and radioactivity to detect mutations, which was a slow and inefficient process.
