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 ...

Polymerase chain reaction (PCR) and rapid (antigen) tests for COVID-19 both involve taking a swab. Results for a PCR test take longer, as it needs to go to a laboratory. It is more costly but tends to ...

A polymerase chain reaction (PCR) test detects genetic material from a pathogen or abnormal cell sample. Ways of collecting samples include a nasal swab, a saliva swab, or taking a sample of blood.

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 ...

The polymerase chain reaction (PCR) has dramatically transformed scientific research and diagnostic medicine. Over the years, PCR has become an indispensable and integral part of clinical and ...
