Students have asked these similar questions
During DNA replication, the leading strand is synthesized continuously, while the lagging strand is synthesized as Okazaki fragments. This is because:
O A. DNA polymerases can bind to only one strand at a time.
O B. Two different DNA polymerases are involved in replication (DNA polymerase I and II).
O C. DNA synthesis can take place only in the 5 -> 3 direction.
D. The primers are made of RNA.
