Role of Taq polymerase in PCR?
Taq polymerase is a heat-stable DNA polymerase enzyme that is crucial in polymerase chain reaction (PCR). It is used to amplify DNA by synthesizing new DNA strands complementary to a template DNA strand at high temperatures. Taq polymerase is derived from the thermophilic bacterium Thermus aquaticus, allowing it to withstand the high temperatures used in PCR without becoming denatured.
Why taq polymerase is thermostable?
Taq polymerase is thermostable because it comes from a bacterium called Thermus aquaticus, which lives in hot springs and has adapted to high temperatures. The enzyme's structure is able to resist denaturation at high temperatures, allowing it to function optimally in PCR reactions that require high temperatures for DNA amplification.
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.

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.
Who is the discoverer of Taq DNA polymerase?
Thomas D. Brock, An American Microbiologist
What is the source of the polymerase used in polymerase chain reaction?
The polymerase used in polymerase chain reaction (PCR) is typically derived from a thermophilic bacterium called Thermus aquaticus. The specific polymerase most commonly used is Taq polymerase, which is known for its ability to withstand high temperatures required for PCR.
Why is a thermostable polymerase used in PCR?
A thermostable polymerase, like Taq polymerase, is used in PCR because it can withstand the high temperatures required for DNA denaturation during each cycle of amplification. This allows the enzyme to remain active throughout the entire PCR process, resulting in efficient and accurate DNA replication.
Why PCR need gelatin?
According to Roche website, different additives allow optimization to increase yield and specificity of PCR reactions. DMSO, for instance, is reported to reduce nonspecific priming, while gelatin and glycerol stabilize Taq DNA polymerase during PCR, which generally increases the yield.
Why are there nucleotides A T G and C in the master mix and what are the other components and what are there functions?
Nucleotides A, T, G, and C are the building blocks of DNA and are included in the master mix for DNA amplification. Other components in the master mix typically include a DNA polymerase enzyme for replication, buffer to maintain optimal pH, and salts to help stabilize the reactions. The DNA polymerase enzyme helps in the amplification process by synthesizing new DNA strands, the buffer maintains the pH for enzyme activity, and salts aid in maintaining the stability of the reaction components.
What is MgCl used for in the polymerase chain reaction?

What does DNA polymerases use as their substrate?
DNA polymerases use deoxyribonucleoside triphosphates (dNTPs) as their substrate to synthesize new DNA strands during DNA replication.
What is the enzyme that synthesized DNA used in PCR that distinguishes it from the equivalent enzyme that carry out the same function in our cells or those of most bacteria?
The enzyme used in PCR to synthesize DNA is called DNA polymerase. The key difference is that the DNA polymerase used in PCR, such as Taq polymerase, is derived from a thermophilic bacterium called Thermus aquaticus and can withstand the high temperatures used in the PCR cycling process. This distinguishes it from the equivalent enzyme in our cells or most bacteria, which would be denatured by the high temperatures of PCR.
