During DNA replication, synthesis of the leading strand of DNA differs from the synthesis of the lagging strand in that ________.

A  only the lagging strand requires a primer for each of the Okazaki fragments; the leading strand does not require a primer to begin synthesis of the daughter strand

B  the leading strand is synthesized continuously toward the replication fork, whereas the lagging strand extends away from the fork and is synthesized in short segments called Okazaki fragments

C  the leading strand is synthesized away from the fork and is made in short segments called Okazaki fragments whereas the lagging strand extends continuously toward the replication fork

D  the leading strand is made in the 5′-3′ direction by DNA polymerase III, whereas the lagging strand is synthesized in the opposite direction, 3′-5′
