   6 de mar. de 2023 · The polymerase chain reaction is a nucleic acid amplification testing procedure that consists of denaturing, renaturing, elongating, and amplifying a short segment of DNA or RNA. This is implemented by incorporating DNA I polymerase, which is derived from Thermus aquaticus, also known as Taq polymerase.

   24 de ago. de 2021 · The polymerase chain reaction (PCR) test for COVID-19 is a molecular test that analyzes your upper respiratory specimen, looking for genetic material (ribonucleic acid or RNA) of SARS-CoV-2, the virus that causes COVID-19. Scientists use the PCR technology to amplify small amounts of RNA from specimens into deoxyribonucleic acid (DNA ...
