In which cloning design is cutting insert with two different enzymes useful?

Answer and explanation

Correct answer: Directional cloning

In directional cloning, the insert and vector are cut with two different restriction enzymes. This produces different, incompatible sticky ends at the two sides, so the insert can ligate into the vector in only one orientation. In non-directional cloning, similar ends may allow insertion in either orientation. Exam tip: two different restriction sites with controlled insert orientation indicate directional cloning.
