Unformatted text preview: w the replication fork. Lagging strand: RNA primer forms near the replication fork. DNA synthesis is towards the origin of replication. •  At origin of replication, break the hydrogen bonds between the two strands. •  Make RNA primers for both strands. •  DNA polymerase makes a new strand in the 5’ to 3’ direction (direction refers to polarity of the NEW strand.) 2 9/21/10 5’ 3’ 5’ 3’ 3’ 5’ 3’ 5’ 5’ 3’ 5’ 3’ 3’ 5’ 3’ 5’ • At origin of replication, break the hydrogen bonds between the two strands. •  At origin of replication, break the hydrogen bonds between the two strands.
