Answer

Brief Explanations:

DNA ligase joins Okazaki fragments on the lagging - strand during DNA replication. A defect in it would majorly affect lagging - strand formation as Okazaki fragments would not be joined together. Helicase unwinds the DNA double - helix for both leading and lagging strands. Single - strand binding proteins stabilize single - stranded DNA for both strands. Topoisomerase relieves the supercoiling of DNA for both strands.

Answer:

A. DNA ligase
