Question

which of the following statements about dna replication is true? multiple choice the leading strand is replicated continuously, while the lagging strand is replicated discontinuously. the leading strand is replicated discontinuously, while the lagging strand is replicated continuously. both the leading and lagging strands are replicated continuously. both the leading and lagging strands are replicated discontinuously.

Explanation:

In DNA replication, the leading strand is synthesized continuously in the 5' - 3' direction as the replication fork opens. The lagging strand is synthesized discontinuously in short fragments called Okazaki fragments because DNA polymerase can only add nucleotides in the 5' - 3' direction and the lagging - strand template is oriented in the opposite direction of the replication fork movement.

Answer:

The leading strand is replicated continuously, while the lagging strand is replicated discontinuously.
