What is the function of the Taq DNA poltmearse in a PCR reaction? What is the purpose of DNA polymerase? A) Adds a ribonucleotide to the 3' end of a growing RNA chain. B) Adds a deoxyribonucleotide to the 5' end of a growing DNA chai...
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 What are the three steps in a PCR cycle, and what does each step accomp...
The real time PCR instrument used for performing amplification must be capable of distinguishing precisely between these fluorescent labels and measuring the signals produced by the amplification of each gene. Typically, the probe for your gene of interest is labeled w...
The first step in a PCR cycle heats the starting sample to almost boiling. The high temperature causes DNA melting, or denaturation—the process of physically breaking down the hydrogen bonds between the two complementary strands of the DNA double helix. The result is two single strands of DNA...
PCR is about finding the smallest necessary fragment of the nucleic acid code of life…and amplifying the number of copies of that target, to the point where it's very easy to detect or quantify. Dmitriy Kosarikov Senior Director, Development Lead - Molecular Diagnostics ...
What is RT-PCR?Paul S. Auerbach
The main advantage of real-time PCR over PCR is that real-time PCR allows you to determine the initial number of copies of template DNA (the amplification target sequence) with accuracy and high sensitivity over a wide dynamic range. Real-time PCR results can either be qualitative (the presen...
