WebA primer is needed to start replication. Leading strand is synthesised continuously. DNA polymerase adds nucleotides to the deoxyribose (3’) ended strand in a 5’ to 3’ direction. 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.
