What is the correct difference between ligase and helicase?

Answer and explanation

Correct answer: Ligase joins DNA fragments and helicase unwinds the DNA double helix

Ligase joins broken DNA ends or DNA fragments by forming phosphodiester bonds. Helicase uses ATP energy to separate the complementary strands of the DNA double helix. Restriction endonucleases, not ligase or helicase, cut DNA at specific sites; therefore A, C, and D are incorrect. Exam tip: remember ligase as the DNA “joining” enzyme and helicase as the DNA “unwinding” enzyme.
