SpletPolymerase chain reaction, or PCR, is a technique to make many copies of a specific DNA region in vitro (in a test tube rather than an organism). PCR relies on a thermostable DNA polymerase, Taq polymerase, and requires DNA primers designed specifically for the DNA region of interest. In PCR, the reaction is repeatedly cycled through a series ...

SpletPCR-based methods may also be cost effective relative to traditional testing procedures. Further advancement of technology is needed to improve automation, optimise detection … SpletPCR Applications — Pathogen Detection. Rapid, sensitive, and highly specific PCR-based detection of pathogen nucleic acids. Molecular methods for detecting pathogens are becoming increasingly popular, as they offer accurate detection at a fraction of the time and effort invested in traditional, culture-based methods. SpletFirst, PCR testing is more sensitive than other methods, such as antigen tests. This means that PCR tests can detect lower levels of the virus in a sample, making them more … intel interview questions and answers
