Why can two different restriction enzymes be used in directional cloning?

Answer and explanation

Correct answer: To create non-identical DNA ends that ligate the insert in a fixed orientation

Two different restriction enzymes generate different, non-compatible sticky ends at the two ends of the vector and insert. Therefore, the insert can ligate into the vector in only one orientation, which is the main purpose of directional cloning. If identical sticky ends were used, the insert could enter in either orientation. Exam tip: Link the use of two enzymes with a fixed insert orientation in directional cloning.
