Which of the following most correctly describes the process of DNA replication?
O The double-stranded DNA molecule being replicated unwinds completely before replication begins.
O Replication of the lagging strand occurs in the 5′ 3′ direction—the leading strand in the 3′ 5′ direction.
O Replication is continuous on the lagging strand and discontinuous on the leading strand.
O The lagging strand is synthesized in segments that are subsequently joined by DNA ligase.
