Polymerase chain reaction (PCR) test kits for COVID-19 use what’s known as gene cloning – not reproductive cloning – to detect the presence or absence of the SARS-CoV-2 virus, but social media posts ...

Genetic modification of mammalian cells has vast use in biotherapeutics development and basic research applications. An important step early on is the isolation of clones with the desired mutation ...

Researchers often call the polymerase chain reaction test – known as the PCR test – "the gold standard" for detecting the COVID-19 virus. The test is considered highly reliable and effective, and it ...
