Cuts the plasmid:
Correct answer: C. DNA ligase
- A. Chimaeric DNA
- B. Takes up recombined plasmid
- C. DNA ligase
- D. Cloned genes
Explanation
DNA ligase is a type of enzyme that facilitates the joining of DNA strands together by catalyzing the formation of a phosphodiester bond. It plays a role in repairing single-strand breaks in duplex DNA in living organisms, but some forms may specifically repair double-strand breaks
