The polymerase chain reaction (PCR) is a relatively simple technique that amplifies a DNA template to produce specific DNA fragments in vitro. Traditional methods of cloning a DNA sequence into a vector and replicating it in a living cell often require days or weeks of work, but amplification of DNA sequences by PCR requires only hours Polymerase chain reaction (PCR) is a method widely used to rapidly make millions to billions of copies of a specific DNA sample, allowing scientists to take a very small sample of DNA and amplify it to a large enough amount to study in detail. PCR was invented in 1983 by the American biochemist Kary Mullis at Cetus Corporation Primer testing through PCR. The accuracy and efficiency of each primer set were verified through PCR amplification of the positive control to optimize the PCR conditions

Gradient PCR for assay optimization is to determine the optimum annealing temperature (Ta) of the primers by testing identical reactions containing a fixed primer concentration, across a range of annealing temperatures When designing the primers for PCR, following things need to be considered: Primers should contain the complementary nucleotides to the flanking end of the DNA that wants to amplify. Primers should have melting temperature between 55 - 65 0 C G and C content should be between 50 to 60%

Premier Diagnostics uses a saliva-based PCR test to detect the COVID-19 virus. To take this test, patients excrete saliva into a sterile test tube provided to them at the testing site. The saliva samples are then collected and transported to a processing lab located in South Jordan, Utah She said the PCR method-based tests are better, but numerous limitations, including financial, restrict its accessibility for mass testing. The most important limitation is that these methods need expensive equipment and a very special setup which is only available in selected hospitals like RITM (Research Institute for Tropical Medicine) and St. Luke's Medical Center, she added PCR primer design. The polymerase chain reaction (PCR) uses a pair of custom primers to direct DNA elongation toward each-other at opposite ends of the sequence being amplified. These primers are typically between 18 and 24 bases in length, and must code for only the specific upstream and downstream sites of the sequence being amplified PCR reaction assembly, PCR execution, and post-PCR analysis. These activities are summa-rized in Figure 1. When arranged in this linear fashion, these activities can be collected into two major groups, the pre-PCR activities (sample preparation and PCR preparation) and the post-PCR activities (PCR execution and analysis) PCR or polymerase chain reaction, is one of the most useful tools in a biologists tool kit. It allows you to take a DNA sample, select a part of it and make.
