Using Reverse Transcription Polymerase Chain Reaction in COVID-19 Testing

This website provides an animated video, from Cold Spring Harbor Laboratory DNA Learning Center and Austin Community College, that briefly discusses the process of polymerase chain reaction (RT-PCR) for COVID-19 testing. PCR "...  amplifies the virus genetic "fingerprint" to detect as few as several virus particles present in a throat swab or other patient sample." This video runs 03:45 minutes in length. The website also includes links to additional resources about COVID-19 testing and PCR.
