Draw a replication fork. Assume that your 3' end is on the left of the upper strand. Select one: a. One of your two leading strands will be synthesized complementary to the lower parental strand, going from the origin of replication towards the 5' end of the parental strand. b. One of your two leading strands will be on the lower strand, synthesized from the origin of replication away from the opening of the fork. c. one of your two leading strands will be synthesized complementary to the upper strand, going from the origin of replication towards the 3' end of the parental strand. d. The leading strand will only be synthesized complementary to the upper strand, away from the opening of the fork.
