How is the bacterium Thermus aquaticus employed in recombinant DNA technology ?

Explanation

**Step-by-Step Solution:**

1. **Introduction to Thermus aquaticus**:
- Thermus aquaticus is a bacterium that thrives in extremely hot environments, such as hot springs, where temperatures exceed 97°C. This unique adaptation allows it to survive and function at high temperatures.

2. **Heat Stability**:
- The key feature of Thermus aquaticus is its heat stability. Unlike many other organisms, it does not denature or lose functionality at high temperatures, which is a crucial characteristic for its application in biotechnology.
