The coupled 5'-3' synthetic/ 3'-5' exonucleolytic action is used most extensively for filling in short single-stranded regions in double-stranded DNA. These regions arise during lagging strand DNA replication.

On the leading strand (sometimes called the forward strand) DNA synthesis can proceed continuously in the 5 ' to 3’ direction as the parental duplex is unwound.

On the lagging strand a stretch of single-stranded parental DNA must beexposed, and then a segment is synthesized in the reverse direction (relative to fork movement).

The lagging strand is synthesized discontinuously and the leading strand is synthesized continuously. This is called semidiscontinuous replication.
