An RNA primer is synthesized, and is elongated by the DNA polymerase. On the leading strand,DNA is synthesized continuously, whereas on the lagging strand, DNA is synthesized in short stretches. The DNAfragments are joined by DNA ligase (not shown).

The process of creating a copy of DNA is referred to as DNA replication. In a eukaryotic cell, this…
