A 1976 discovery of Taq polymerase a DNA polymerase purified from the thermophilic bacterium, Thermus aquaticus, which naturally occurs in hot (50 to 80 °C (120 to 175 °F)) environments[8] paved the way for dramatic improvements of the PCR method.
(See Poly(A) polymerase, Polymerase chain reaction, RNA polymerase, Taq polymerase.) Polymorphisms. Variant forms of a particular gene that occur simultaneously in a population. Polynucleotide. A DNA polymer composed of multiple nucleotides.
Taq polymerase is widely used in current PCR practice (May 2004). A disadvantage of Taq is that it sometimes makes mistakes when copying DNA, leading to mutations (errors) in the DNA sequence, since it lacks 3'-5' proofreading exonuclease activity.
The polymerase is called Taq polymerase. It is call Taq because it comes from the organism Thermus aquaticus, a bacteria that lives in thermal vents in the ocean.
Use of a thermostable DNA polymerase (such as Taq polymerase) allows the reactions to be perfo rmed in a thermocycler that automatically adjusts the temperature to the optimal for each reaction through many cycles.
It's DNA polymerase (called Taq polymerase) is stable at relatively high temperatures and functions optimally at 70 degrees C. This is important because high temperatures will be used to separate the strands of the double helix.
