Answer: The correct answer would be 5'-3' direction.
Explanation:
DNA polymerase is the enzyme used for replication of DNA. It adds nucleotide to 3'-OH of growing nucleotide chain. The nucleotides are added based on the complementary base-pairing rule.
During DNA replication, primase adds a RNA primer opposite to parent DNA strand. The primer provides free 3'-OH to which DNA polymerase adds nucleotides according to the base-pairing.
