Source of Taq polymerase:
Correct answer: A. Thermus aquaticus
- A. Thermus aquaticus
- B. Thermus floral
- C. Floral aquaticus
- D. Taq aquaticus
Explanation
Taq polymerase is a heat-stable DNA polymerase that is used in the polymerase chain reaction (PCR) to amplify DNA. It was originally isolated from the bacterium Thermus aquaticus, which is found in hot springs and other high-temperature environments. Taq polymerase is able to withstand the high temperatures required for the denaturation of double-stranded DNA during PCR, making it a valuable tool for molecular biology.
