Polymerase chain reaction (PCR) is a laboratory procedure that can create replicas of DNA. Explore the three steps of this revolutionary process: denaturation, annealing, and extension. Related to this Question How does PCR work? Can PCR work with a single-stranded DNA template?
PCR is able to make multiple copies of a single target region of a gene through numerous PCR cycles over a short period of time. After 25-30 PCR cycles, 10000000 copies of a single target gene can be amplified. The instrument named thermal cycler is used to perform PCR. There are severa...

After adding the nucleic acid to be detected, the reaction system performs a fluorescent PCR amplification reaction. The time is slightly different depending on the PCR reagents and instruments used. Generally,it takes 90-120 mi...
Genotyping by PCR The two most common PCR methods to detect SNPs are amplification refractory mutation system PCR (ARMS PCR) and real-time PCR (qPCR). ARMS PCR For ARMS PCR, also called allele-specific PCR, you need to add four different primers to your master mix. The first primer pair...

Cells or tissues are crosslinked to preserve chromatin–protein interactions, and the protein of interest is immunoprecipitated with an antibody. Quantification of the precipitated DNA by PCR or profiling methods indicates enrichments of the protein of interest. Chromatin remodelers Enzymes or complexes ...
Enter the "vaccine passport." In this brief primer we'll help you understand just what is a vaccine passport, how does it function, and where can you expect to need it. This is our explainer on the rise of the COVID-19 vaccine passport. ...
This modified DNA is able to successfully replicate and infect the second host, but since that host does not contain the same modification system as the first, the modified phage lose their ability to replicate on the original host. In 1968, Arber and Linn demonstrated nuclease activity of Eco...
—How deadly is the new coronavirus?—How does the coronavirus spread?—Can people spread the coronavirus after they recover? The COVID-19 tests developed by the Centers for Protection and Disease Control (CDC), as well as those developed in Washington and New York, are PCR tests. Sign up...
