WebIts DNA polymerase is very heat-stable and is most active around 70 °\text C 70°C (a temperature at which a human or E. coli DNA polymerase would be nonfunctional). This heat-stability makes Taq polymerase ideal for PCR. As we'll see, high temperature is used … Gel electrophoresis is a technique used to separate DNA fragments (or other … DNA cloning is the process of making multiple, identical copies of a particular … Its ingredients are similar to those needed for DNA replication in an organism, or for … Many examples of modern biotechnology depend on the ability to analyze, … The most important enzyme in a PCR reaction is called taq polymerase. A … WebIn PCR, the enzyme that’s normally used works at very high temperatures: 72° is its optimum, and it can survive 90° long enough to allow the denaturing step to occur. The DNA polymerase most commonly used in PCR is called Taq, which is short for Thermus aquaticus, the heat-loving bacterium from which the enzyme was first isolated. Repeat
Web1 Jul 2004 · Initial denaturation was for 3 min at 95 °C to activate the enzyme, after which 30–50 cycles of amplification were performed with denaturation at 95 °C for 30 s, annealing at primer-specific temperatures (mOT-R, 68 °C; S27a, 60 °C) for 10 s, and elongation at 72 °C for 30 s. Fluorescence data were acquired after 10 s at 80 °C.
