The taq polymerase enzyme is obtained from

Options

A. Bacillus subtilis
B. Pseudomonas putida
C. Thermus aquaticus
D. Thiobacillus ferroxidans

Answer

**Step-by-Step Text Solution:**

1. **Identify the Enzyme**: The question asks about the source of the Taq polymerase enzyme.

2. **Recognize the Source Organism**: Taq polymerase is derived from a specific organism known for its ability to withstand high temperatures.

3. **Determine the Correct Organism**: The organism that produces Taq polymerase is *Thermus aquaticus*, a thermophilic bacterium that thrives in hot environments.

4. **Understand the Importance of Taq Polymerase**: Taq polymerase is crucial for the Polymerase Chain Reaction (PCR), a technique used to amplify DNA.

5. **Explain the Role in PCR**: In PCR, the first step is denaturation, where double-stranded DNA is separated into single strands. This process requires high temperatures (around 96°C), which is why Taq polymerase, capable of functioning at these temperatures, is used.

6. **Eliminate Incorrect Options**: The other options provided (Thiobacillus thiooxidans, Pseudomonas aeruginosa, and Bacillus subtilis) do not produce Taq polymerase.

7. **Conclude the Answer**: Therefore, the correct answer to the question is that Taq polymerase is obtained from *Thermus aquaticus*.
