What is the role of Taq polymerase?
Taq polymerase denotes the heat-stable DNA polymerase extracted from the thermophilic bacteria Thermus aquaticus. It is used to automate the repetitive steps in the polymerase chain reaction (PCR) technique, an extremely important method of amplifying specific DNA sequences.
What is Taq polymerase and why is it used in PCR?
“The function of Taq DNA polymerase in PCR is to amplify or synthesize DNA or gene of interest for various downstream applications. It’s a type of thermostable DNA polymerase, work at a higher temperature as well.”
What is the difference between DNA polymerase and Taq polymerase?
DNA polymerase is an enzyme that creates new DNA from its building blocks (nucleotides). The key difference between Taq polymerase and DNA polymerase is that Taq polymerase can withstand high temperatures without denaturing while other DNA polymerases denature at high temperatures (at protein degrading temperatures).
What is Taq polymerase and where does it come from?
Taq DNA Polymerase was originally isolated from thermophilic bacterium of the Deinococcus-Thermus group located near the Lower Geyser Basin of Yellowstone National Park by Thomas D. Brock and Hudson Freeze, in 1969. This thriving bacterium was named Thermus aquaticus (T. aquaticus).

Why is Taq polymerase special?
Taq makes DNA products that have A (adenine) overhangs at their 3′ ends. Also, Taq DNA Polymerase is the standard for routine PCR. It is “special” because it comes from the bacterium Thermus aquaticus, which lives in hot springs. So it is thermostable even at high temperatures, while other polymerases (eg E.
Why is the DNA heated to 94c?
Denaturation. When a double stranded DNA (dsDNA) molecule is heated to 94oC, the paired strands will separate (denature), by breakage of hydrogen bonding present between complimentary bases, resulting the single stranded DNA formation. This allows the primers access to the single stranded DNA (ssDNA) templates.
What is the advantage of Taq polymerase in PCR?
Thermostability: Taq polymerase is a thermostable DNA polymerase isolated from a bacterium that lives in hot springs. It can withstand the high temperature of >90°C required for the denaturing step in PCR and remain enzymatically active after each cycle.
Where is Taq polymerase found?
…a heat-stable DNA polymerase called Taq, an enzyme isolated from the thermophilic bacterium Thermus aquaticus, which inhabits hot springs.
Who produces Taq polymerase?
Swapping out the vestigal domain for a functional one from E. coli created a protein with proof-reading ability but a lower optimal temperature and low thermostability. Versions of the polymerase without the 5′-3′ exonuclease domain has been produced, among which Klentaq or the Stoffel fragment are best known.
Where do we get Taq polymerase?
Is Taq polymerase DNA dependent?
Taq DNA polymerase, one of the first thermostable DNA polymerases to be discovered, has been typecast as a DNA-dependent DNA polymerase commonly employed for PCR.
