DNA polymerase is a temperature-insensitive enzyme extracted from:
Correct answer: B. Thermus aquaticus
- A. Fishelsoni
- B. Thermus aquaticus
- C. E. Coli
- D. Both Fishelsoni and Thermus aquaticus
Explanation
Thermus aquaticus is a bacterium that lives in hot springs, and hydrothermal vents, and Tqa polymerase was identified as an enzyme able to withstand the protein-denaturing conditions like high temperature required during PCR. Therefore is the source of the DNA polymerase used in the PCR technique.
