The enzyme that seals the foreign piece of DNA into the vector is called:
Correct answer: C. DNA ligase
- A. DNA polymerase
- B. DNA helicase
- C. DNA ligase
- D. DNA primase
Explanation
DNA ligase is the anzyme that joins DNA fragments by forming phosphodiester bonds, effectively sealing a foreign piece of DNA into a vector.
