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 ...

DNA is often used to identify mysterious materials or match a suspect with a crime. However, identification can be slowed while a trace amount of DNA is increased so there will be enough to test.

When creating a PCR protocol, users normally concentrate on the template DNA, reaction mix (buffer, dNTPs, taq polymerase), primers, probes, and the thermocycler, which is the main instrument used to ...

DNA analysis is a crucial tool for identifying harmful pathogens, such as bacteria, viruses, or fungi, that cause infections.
