The Correct Option is A
Solution and Explanation
Step 1: Understanding the Restriction Sites in pBR322
- The pBR322 plasmid contains two antibiotic resistance genes:
- Ampicillin resistance (bla gene).
- Tetracycline resistance gene.
- The BamHI restriction site is present in the tetracycline resistance gene, which allows for gene insertion.
- The pBR322 plasmid contains two antibiotic resistance genes:
- Ampicillin resistance (bla gene).
- Tetracycline resistance gene.
