Recombinant DNA is achieved by cleaving the pro-DNAs by:
Correct answer: B. Restriction endonulcease
- A. Ligase
- B. Restriction endonulcease
- C. Primase
- D. Exonucleases.
Explanation
Recombinant DNA is the product obtained after isolating a specific DNA segment and then inserting it into another DNA molecule at a desired position. Restriction endonucleases are the enzymes that digest DNA at specific sites to isolate a specific DNA segment. Thus they are required for producing recombinant DNA.
