Unwinding and replication ffi Continuous DNA synthesis begins at the 3' end of the broken nucleotide strand.
^ As the DNA molecule unwinds, the 5' end is progressively displaced.
(c) Linear eukaryotic replication ffi At each fork, synthesis of the leading strand takes place continuously in the same direction as that of unwinding.
