DNA polymerase can catalyze a dehydration synthesis reaction only at the 3' carbon of the daughter strand of DNA. This means that
A. Okazaki fragments extend toward the replication fork as the parent strands are unzipped by helicase.
B. the leading and lagging strands extend in the 3' - 5' direction toward the replication fork as the nucleotide bases are exposed.
C. since the strands are antiparallel, one strand will grow toward the fork as it opens, and the other strand will grow in fragments away from the fork.
D. the antiparallel nature of the parent molecules determine that the leading strand must be grown in fragments away from the fork and the lagging strand is synthesized continuously toward the fork.
