Double stranded DNA has been separated to be replicated. The blue circles represent the origin of replication. The arrow represents the direction of movement of the replication fork. The 5’ and 3’ ends of the two template strands are indicated. The letters A and B show where new DNA daughter strands will be synthesized. Which section will be replicated continuously to produce a leading daughter strand, and which section will be replicated as Okazaki fragments to produce a lagging daughter strand?
