What is one advantage of PCR compared to other detection techniques?

The advantage of PCR (polymerase chain reaction) compared to other detection techniques lies in its ability to offer very high sensitivity. PCR is designed to amplify small amounts of DNA, making it possible to detect even minute quantities of genetic material. This level of sensitivity allows researchers and technologists to identify the presence of pathogens, genetic mutations, or specific DNA sequences that may be present in very low concentrations. Because of this high sensitivity, PCR is widely used in medical diagnostics, forensic analysis, and genetic testing, which can be crucial in situations where low levels of target nucleic acids must be detected.

Other detection techniques may lack this level of sensitivity and may require higher concentrations of the target material to yield detectable results, making PCR particularly valuable in clinical and research settings.
