Taq polymerase enzyme is a:

Options

A. DNA polymerase obtained from a bacterium
B. DNA polymenasc obtained from a fungi
C. RNA polymerase obtained from a bacterium
D. RNA polymerase obtained from a fungi

Answer

**Step-by-Step Solution:**

1. **Understanding Taq Polymerase**: Taq polymerase is an enzyme that plays a crucial role in the process of DNA replication. It is specifically known for its ability to withstand high temperatures.

2. **Identifying the Type of Polymerase**: Taq polymerase is classified as a DNA polymerase. This means it synthesizes DNA molecules from nucleotides, the building blocks of DNA.

3. **Thermal Stability**: One of the key features of Taq polymerase is its thermal stability. It can function effectively at elevated temperatures, which is essential for techniques like the Polymerase Chain Reaction (PCR), where the DNA is subjected to high temperatures to denature (separate) the strands.

4. **Source of Taq Polymerase**: Taq polymerase is derived from a specific bacterium known as *Thermus aquaticus*. This bacterium thrives in hot environments, which is why its polymerase is heat-resistant.

5. **Conclusion**: Based on the above points, Taq polymerase is a DNA polymerase obtained from a bacterium.

**Final Answer**: Taq polymerase enzyme is a DNA polymerase obtained from a bacterium.
