The RNA primer is removed in a
3^(')
to
5^(')
direction. DNA polymerase requires a primer for DNA synthesis. The lagging strand is synthesized from the hydroxyl end to the phosphate end. DNA ligase links the
5^(')OH

3^(')
phosphate group of an adjacent fragment. DNA polymerase synthesizes DNA from the phosphate end to the hydroxyl end.
