In a eukaryotic cell, DNA replication occurs during the S phase of the cell cycle. Outline the roles of DNA polymerase and DNA ligase in this process, explaining why the lagging strand is synthesised discontinuously.

Nucleic acids and protein synthesis: outline question
Outline4 marksStandard
How this question is marked
4 marks, so the mark scheme is looking for about 4 separate creditworthy points. Making the same point twice in different words earns it once.
Outline means: Give the main points briefly. Less detail than describe, but every key step has to be there. One short line per step, in order. The marks are for coverage, not depth.
