When the lagging daughter strand of DNA is synthesized, unreplicated gaps are formed on the parental DNA. Lagging strand synthesis fills these gaps by
A) synthesizing short Okazaki fragments in a 5´-to-3´ direction.
B) synthesizing multiple short RNA primers to initiate DNA replication.
C) using DNA polymerase I to remove RNA primers from Okazaki fragments.
D) filling in those gaps with new strands of complementary DNA as the replication fork proceeds.
E) All of the above

Lagging strand synthesis involves all these processes: Okazaki fragments are synthesized in a 5'-to-3' direction, RNA primers are used to initiate synthesis, DNA polymerase I removes RNA primers, and gaps are filled with complementary DNA.
