Discussion :: Recombinant DNA - Section 1 (Q.No.23)

23. 

The advantage of using DNA polymerases from thermophilic organisms in PCR is that

[A]. the DNA polymerases of these bacteria are much faster than those from other organisms
[B]. the DNA polymerases of these bacteria can withstand the high temperatures needed to denature the DNA strands
[C]. the DNA polymerases of these bacteria never make mistakes while replicating DNA
[D]. all of the above

Answer: Option B

Thermophilic as the name suggests, are -heat loving organisms. They have the ability to withstand high conditions of temperature. DNA pols from these organisms are widely used.

Denaturation of DNA means separating two strands of DNA by using some bacterias at temp 94 to 95-degree celsius.

Noumal Hassni said: (Jul 16, 2020)  
The polymerase chain reaction is a thermo-cycling process involving high temperature as 94°C, DNA polymerase of thermophilic bacteria can survive such temperature. An example is a commonly used Taq-polymerase enzyme isolated from Thermophylus aquatics.
