Study Notes
Cloning Vector
- A cloning vector is a small DNA molecule that is capable of replicating independently in a host cell.
- The main purpose of a cloning vector is to carry a foreign DNA fragment into a host cell, where it can be replicated and expressed.
- A characteristic of a cloning vector is that it has a unique restriction site that allows for the insertion of foreign DNA.
- A cloning vector is not a natural part of a host cell's genome, but rather a tool used in genetic engineering.
- Not a characteristic of a cloning vector is that it is a catalyst in a chemical reaction.
