What would happen if a plasmid without a selectable marker was chosen as a cloning vector?

Explanation

### Step-by-Step Solution:

1. **Understanding Plasmids and Selectable Markers**:
- A plasmid is a small, circular piece of DNA that can replicate independently of chromosomal DNA in bacteria.
- A selectable marker is a gene included in the plasmid that allows for the identification of cells that have successfully taken up the plasmid.

2. **Role of Selectable Markers in Cloning**:
- When a plasmid with a selectable marker is introduced into a bacterial population, only those bacteria that have taken up the plasmid can survive in the presence of a specific antibiotic (or other selective conditions).
