What will happen if a plasmid vector is digested with EcoR1 at a single site?

Explanation

**Step-by-Step Solution:**

1. **Understanding Plasmid Vectors**: A plasmid vector is a small, circular DNA molecule that is used to carry foreign DNA into a host cell. It is commonly used in genetic engineering.

2. **Role of EcoR1**: EcoR1 is a restriction enzyme that recognizes specific sequences in DNA and cuts it at those sites. It is known for creating "sticky ends" when it cuts DNA.

3. **Digesting the Plasmid Vector**: If a plasmid vector is digested with EcoR1 at a single site, the enzyme will cleave the DNA at that specific location.
