If eukaryotic cells evolved such that lagging strand DNA synthesis could occur continuously (without the use of Okazaki fragments), what enzyme would likely no longer be needed for DNA replication?
A) Flap endonuclease
B) Helicase
C) Primase
D) Topoisomerase

Flap endonuclease is involved in processing Okazaki fragments during lagging strand synthesis. If lagging strand synthesis were continuous, Okazaki fragments would not form, eliminating the need for flap endonuclease.
