WebMar 17, 2024 · Taq DNA Polymerase is a highly thermostable recombinant DNA polymerase. It is named after Thermus aquaticus, the heat-tolerant bacterium from which it isolates itself. The molecular weight of the Taq Polymerase is 94kD, and it amplifies DNA up to 5kb with an elongation velocity of 0.9-1.2kb/min at 70-75°C. What is Polymerase Chain … Most life-forms on Earth live at temperatures of less than 50 °C, commonly from 15 to 50 °C. Within these organisms are macromolecules (proteins and nucleic acids) which form the three-dimensional structures essential to their enzymatic activity. Above the native temperature of the organism, thermal energy may cause the unfolding and denaturation, as the heat can disrupt the intramolecula…
