PCR is a technique used to selectively amplify a region of DNA from a mixed template. Reagents are added to special thin-walled tubes, mixed and centrifuged, loaded in the thermal cycler for the duration of the thermal cycling program, cooled, and evaluated by agarose gel elect...
PCR is an acronym for polymerase chain reaction. It is a technique which is used to copy DNA. This technique has been extremely useful for research in molecular biology and genetic testing. Answer and Explanation: Learn more about this topic: ...
PCR is a ubiquitous laboratory technique of molecular biology used to amplify a target DNA sequence to millions of copies. At the inception of the technology in the early 1980s, DNA amplification by PCR was a time-consuming and laborious process. T...
PCR has a myriad of applications. In medicine, it is used for diagnosing genetic diseases, identifying infectious agents like viruses and bacteria, and monitoring the effectiveness of treatments. Forensic scientists use PCR to analyze DNA evidence from crime scenes, aiding in criminal investigations an...
