Enzyme Taq polymerase is obtained from

Options

A. Thermus aquaticus
B. Trichoderma aquatica
C. Tremetes aquaticus
D. All the above

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the source of Taq polymerase, a specific enzyme used in biotechnology, particularly in PCR (Polymerase Chain Reaction).

2. **Identifying the Options**: The options provided are:
- Thermus aquaticus
- Trichoderma aquatica
- Trematus aquaticus
- All of the above

3. **Researching Taq Polymerase**: Taq polymerase is known to be a thermostable DNA polymerase. It is crucial for its ability to withstand high temperatures during the PCR process.

4. **Historical Context**: Taq polymerase was originally isolated by Thomas D. Brock in 1965. This historical context is important as it helps identify the correct source of the enzyme.

5. **Source Identification**: The enzyme was isolated from a thermophilic bacterium, which is a type of bacteria that thrives at high temperatures. The specific bacterium from which Taq polymerase is derived is **Thermus aquaticus**.

6. **Conclusion**: Based on the information gathered, the correct answer to the question is that Taq polymerase is obtained from **Thermus aquaticus**.

**Final Answer**: Taq polymerase is obtained from **Thermus aquaticus**.
