Which enzyme is used to join bits of DNA?
Answer: B
Correct answer: DNA ligase
DNA ligase forms the phosphodiester bond that closes a nick between two adjacent fragments. It is what joins Okazaki fragments in the cell, and what joins an insert to a vector in cloning. Polymerase extends a chain from a primer; endonucleases and primases cut and prime respectively.
