Taq Polymerase is an important enzyme component involved in the PCR reaction. Its A DNA polymerase and its role is to elongate the growing strands of DNA during the extension process. Since the Extension process in a PCR works at a temperature which a human DNA polymerase cannot remain active, the Taq polymerase obtained from Thermus aquaticus (living in the hot springs) are used and hence these enzymes are thermo stable.

Why taq polymerase is strored at very low temperature as it is thermostable?

Storing Taq polymerase at a very low temperature (typically -20°C) helps preserve its activity over time. While Taq polymerase is thermostable and can withstand high temperatures during PCR, storing it at low temperatures helps prevent degradation and denaturation of the enzyme, leading to better performance in PCR reactions.


Why is a thermostable polymerase used in PCR?

The thermostable polymerase (or Taq polymerase) is a thermostable DNA polymerase (named after the thermophilic bacterium Thermus aquaticus from which it was originally isolated by Thomas D. Brock in 1965), is often abbreviated to "Taq Pol" (or simply "Taq"), and is frequently used in polymerase chain reaction (PCR). Taq polymerase is as an enzyme able to withstand the protein-denaturing conditions (high temperature) required during PCR; Therefore it replaced the DNA polymerase from E. coli originally used in PCR. Taq's optimum temperature for activity is 75-80°C, with a half-life of greater than 2 hours at 92.5°C, 40 minutes at 95°C and 9 minutes at 97.5°C, and can replicate a 1000 base pair strand of DNA in less than 10 seconds at 72°C.


What is thermostable DNA polymerase?

Thermostable DNA polymerase is an enzyme that can withstand high temperatures, typically used in PCR (polymerase chain reaction) to amplify DNA. The most well-known example is Taq polymerase, which is isolated from the thermophilic bacterium Thermus aquaticus. Its ability to function at high temperatures allows for the repeated cycles of heating and cooling necessary for PCR.


How did Taq DNA polymerase acquire its name?

The Taq name is a shortened for Thermophilus aquaticus, a thermophilic bacteria that is the source of the particular DNA polymerase enzyme. The enzyme heat resistant property is desired because it could withstand the high temperature during the PCR process. -Kaitlin The Taq name is a shortened for Thermophilus aquaticus, a thermophilic bacteria that is the source of the particular DNA polymerase enzyme.

What is the recommended extension time for Taq polymerase in PCR amplification?

The recommended extension time for Taq polymerase in PCR amplification is typically 1 minute per kilobase of DNA being amplified.

Could you use human polymerase for the extension step in the PCR reaction?

Actually the problem with the Human polymerase is the sensitivity to temperature if we talk about PCR. That is the reason why we use Taq DNA polymerase which is thermostable where as use of human polymerase may result in loss of its function due to high temperature.


What is the significance of thermostable polymerase in DNA technology?

Thermostable polymerase, like Taq polymerase, is important in DNA technology because it can withstand the high temperatures used in polymerase chain reaction (PCR). This allows for the rapid amplification of DNA fragments without the need to constantly replenish the enzyme. This polymerase is derived from thermophilic bacteria and is essential for the success of PCR in molecular biology applications.


Is vent polymerase a thermostable enzyme?

Yes, Vent polymerase is a thermostable enzyme. It is derived from the Thermococcus species and is able to withstand high temperatures, making it suitable for use in applications that require high-temperature conditions such as polymerase chain reaction (PCR).


Role of Taq polymerase in PCR?

taq polymerase is special because it is very stable at high temperatures and will not denature even at the 90 degree step of pcr. taq polymerase is so heat stable because it was extracted from the bacterium thermus aquaticus, which is found in hot springs and geezers

What are the benefits of using Taq polymerase in PCR?

Taq polymerase is beneficial in PCR because it is heat-resistant, allowing for the high temperatures needed to separate DNA strands. This enzyme also has a high replication rate, leading to faster PCR cycles. Additionally, Taq polymerase is cost-effective and widely available, making it a popular choice for PCR experiments.
