Many cancers are characterized by small mutations in certain genes, and this is what PCR is employed to identify. COVID-19 is an emerging, rapidly evolving situation. It is also known as a quantitative polymerase chain reaction (qPCR), which is a laboratory technique of molecular biology based on the polymerase chain reaction (PCR). Nested polymerase chain reaction is a modification of polymerase chain reaction intended to reduce non-specific binding in products due to the amplification of unexpected primer binding sites.

Applications of Nested PCR: It is a worthy process used from long time in pathology labs for microorganism detection as: For the detection of Bartonella, Rickettsia and many organisms in tissues and blood (bacteremia). To investigate the structure of ciliate communities, we developed a nested PCR-DGGE method, which combines a universal eukaryotic-specific primer set in the first PCR step with a ciliate-specific primer set in the second PCR step, to amplify 18S rRNA genes from ciliates. PCR is used in the analysis of mutations that occur in many genetic diseases (e.g. Genetic diversity of Flavobacterium psychrophilum recovered from commercially raised rainbow trout, Oncorhynchus mykiss (Walbaum), and spawning coho salmon, O. kisutch (Walbaum). Periodontal disease and atherosclerotic vascular disease: does the evidence support an independent association? Disadvantages of nested PCR: The method is time-consuming.
