?
The RNA primer is removed in a
3^(')
to

direction.
DNA polymerase requires a primer for DNA synthesis.
The lagging strand is synthesized from the hydroxyl end to the phosphate end.

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