How can a repetitive amplification be achieved?

Explanation

### Step-by-Step Solution:

1. **Understanding Repetitive Amplification**:
- Repetitive amplification refers to the process of creating multiple copies of a specific DNA segment. This is crucial in various applications, including genetic analysis and forensic science.

2. **Polymerase Chain Reaction (PCR)**:
- The primary method used for repetitive amplification is the Polymerase Chain Reaction (PCR). PCR is a technique that allows for the exponential amplification of DNA.
