What are the steps to perform PCR

Answered By: Lucas Baker Date: created: Dec 11 2021

A standard polymerase chain reaction (PCR) setup consists of four steps:

  1. Fill PCR tubes with the necessary reagents or mastermix and the template.
  2. Combine, then centrifuge.
  3. According to the thermo cycler and primer parameters, amplify.
  4. Use agarose gel electrophoresis and ethidium bromide staining to analyze amplified DNA.
