Question 9

The following events occur during the eukaryotic cell cycle:

  • Event W: Rapid protein synthesis and the replication of organelles (such as mitochondria).
  • Event X: Semiconservative replication of nuclear DNA.
  • Event Y: Separation of sister chromatids to opposite poles of the spindle.
  • Event Z: Division of the cytoplasm to form two separate daughter cells.

Which option correctly describes a chronological sequence of these events?
