A plasmid DNA and linear DNA (both are of the same size) have one site for restriction endonuclease. When cut and separated on agarose gel electrophoresis, plasmid shows one DNA band, while linear DNA shows two fragments Explain.

Explanation

**Step-by-Step Solution:**

1. **Understanding Plasmid and Linear DNA**:
- Plasmid DNA is typically circular in shape, while linear DNA is straight and has terminal ends. Both types of DNA can be cut by restriction endonucleases at specific sites.

2. **Role of Restriction Endonucleases**:
- Restriction endonucleases are enzymes that cut DNA at specific sequences. In this case, both the plasmid and linear DNA have one site for the restriction endonuclease.
