WebJan 15, 2024 · In general, DNA is replicated by uncoiling of the helix, strand separation by breaking of the hydrogen bonds between the complementary strands, and synthesis of two new strands by … Web9. One strand is replicated in a continuous manner in the same direction as the replication fork (leading strand) 10. The other strand is replicated discontinuously and in fragments (Okazaki fragments) in the opposite direction (lagging strand) 11. DNA Polymerase I removes the RNA primer and replaces it with DNA. 12.
