Question 8 1 pts The enzyme helicase always moves from 5' to 3' is responsible for synthesizing new strands of DNA will be loaded twice at each origin of replication. Once for each replication fork. always moves from 3 to 5' is responsible for unwinding and separating the two strands of DNA to allow each to serve as a template for replication
