Question 1 • Anatomy & Physiology A

What is the order in which the replication enzymes assist with DNA replication?

Answer
A
helicase, ligase, DNA polymerase
B
helicase, DNA polymerase, ligase
C
DNA polymerase, helicase, ligase
D
DNA polymerase, ligase, helicase

Explanation

Helicase acts first by unwinding and separating the DNA strands. DNA polymerase then builds new complementary strands by adding nucleotides. Ligase joins DNA fragments together, helping complete the new strands. Therefore, the order is helicase, DNA polymerase, ligase.
