How is action of normal endonuclease enzymes different from restriction endonuclease?

Explanation

### Step-by-Step Solution:

1. **Definition of Endonucleases**:
- Endonucleases are enzymes that cut the DNA strands. They can be classified into two categories: normal endonucleases and restriction endonucleases.

2. **Action of Normal Endonucleases**:
- Normal endonucleases cut only one strand of the DNA duplex. This means they do not cleave both strands simultaneously, which is crucial for their function in processes like DNA repair.
