The elongation of the leading strand during dna synthesis a) progresses away from the replication fork. b) occurs in the 3' → 5' direction. c) produces okazaki fragments. d) depends on the action of dna polymerase. e) does not require a template strand.

The only correct one is D - depends on the action of DNA polymerase.

A - no progresses towards the replication fork (the "fork" opens up as elongation moves towards it)

B - the DNA template is READ in the 3' - 5' direction, but it is BUILT in the 5' - 3' direction

C - Okazaki fragments are only made on the lagging strand (because it is hard to make the DNA on that strand

D - YEP

E - Absolutely requires a template strand (otherwise we wouldn't exist!)

the answer to your question is:

c. complementary base-pairing
