DNA polymerase can operate only on a DNA template in its 3´ → 5´ direction, assembling a 5´ → 3´ complementary strand. It cannot initiate replication; rather, it requires RNA primase to attach short segments of RNA nucleotides before the DNA polymerase can begin. As a result, DNA polymerase can operate continuously on one DNA strand (3´ → 5´) toward the replication fork but only in short segments away from the replication fork on the second DNA strand (5´ → 3´). These short segments made from the second DNA strand are later joined by DNA ligase.
