Name the technique used for separating DNA fragments in the laboratory.

Explanation

**Step-by-Step Solution:**

1. **Understanding DNA Fragmentation**:
- DNA is often fragmented using enzymes known as restriction endonucleases. These enzymes cut the DNA at specific sequences, resulting in smaller DNA fragments.

2. **Separation of DNA Fragments**:
- The fragmented DNA is not visible to the naked eye. To separate and visualize these fragments, a technique called gel electrophoresis is employed.
