Lagging Strand

A strand of DNA that is synthesized as a series of short segments, called Okazaki fragments, which are then covalently joined by DNA ligase. Compare with leading strand.

Leading Strand

Strand of DNA that is synthesized continuously. Compare with lagging strand.

Okazaki Fragment

One of many short segments of DNA, each 100 to 1000 nucleotides long, that must be joined by DNA ligase to form the lagging strand in DNA replication.
