Correct answer: B

Ligases join the two DNA molecules. DNA ligase is an enzyme which can connect two strands of DNAtogether by forming a bond between the phosphate group of one strand and the deoxyribose group on another. It is used in cells to join together the Okazaki fragments which are formed on the lagging strand during DNA replication.
