2.2. Taq DNA polymerase is the most common enzyme used for PCR amplification. This enzyme is extremely heat resistant with a half-life of 40 minutes at 95°C. At its optimal temperature (72°C), nucleotides are incorporated at a rate of 2–4 kilobases per minute.
What happens at 72 degrees Celsius during PCR?
72⁰C is the optimum temperature for the Taq polymerase to build the complementary strand. It attaches to the primer and then adds DNA bases to the single strand one-by-one in the 5' to 3' direction. The result is a brand new strand of DNA and a double-stranded molecule of DNA.21 Jul 2021
Why the temperature 72 C is optimized for the Taq polymerase enzyme used for PCR?
75-80 degree Celsius
What is Taq polymerase used for?
Taq DNA Polymerase, or Taq polymerase, is an enzyme and biological catalyst involved in the attachment of nucleotides to synthesize DNA––like any other polymerase.21 Jul 2021
What is the function of Taq?
The function of Taq DNA Polymerase: The Taq has a function to synthesize/amplify/copy the DNA. You may wonder how Taq does do Polymerization? The present enzyme has stable polymerization activity at temperatures between 70°C and 78°C and may even increase by adding some salts.2 Oct 2018
Why is Taq used in PCR?
The DNA polymerase typically used in PCR is called Taq polymerase, after the heat-tolerant bacterium from which it was isolated (Thermus aquaticus). This heat-stability makes Taq polymerase ideal for PCR. As we'll see, high temperature is used repeatedly in PCR to denature the template DNA, or separate its strands.
Why is Taq important to industry?
A taq enzyme is a bacterial enzyme that functions in the manufacture of deoxyribonucleic acid (DNA ). All bacteria possess DNA polymerase. The reason that the taq polymerase has become so significant to biotechnological processes is because of the resistance of the enzyme to heat.

Why is Taq polymerase special?
Taq DNA polymerase is the most common enzyme used for PCR amplification. This enzyme is extremely heat resistant with a half-life of 40 minutes at 95°C. This will result in the amplification of non-specific targets that can be overcome by the use of a 'hot-start' PCR technique (Mullis 1991).
