Which of the following is a selectable marker used in the pBR322 plasmid vector?
- A.
- B.
- C.
- D.
Show correct answer & step-by-step solution
Correct answer: A —
Solution
- Selectable markers are genes that allow the identification of transformants.
- The plasmid contains two antibiotic resistance genes: and .
- The site controls replication, while codes for proteins involved in plasmid replication.
- is a restriction site, not a selectable marker.
- Hence the answer is (A).
