How do the leading, and the lagging strands differ? A. The leading strand is synthesized in the same direction as the movement of the replication fork, and the lagging strand is synthesized in the opposite direction. B. The leading strand is synthesized at twice the rate of the lagging strand. C. The leading strand is synthesized in short fragments that are ultimately stitched together, whereas the lagging strand is synthesized continuously. D. The leading strand is synthesized by adding nucleotides to the 3′ end of the growing strand, and the lagging strand is synthesized by adding nucleotides to the 5′ end. © 2016 Pearson Education, Inc.
