Question 9

A student is studying the progression of a eukaryotic cell through the cell cycle and records five distinct cellular events:

  • Event I: Semiconservative replication of nuclear DNA.
  • Event II: Transcription of tubulin genes and accumulation of ATP reserves.
  • Event III: Centromeres split and sister chromatids are pulled to opposite spindle poles.
  • Event IV: Constriction of an actin-myosin contractile ring to partition the cytoplasm.
  • Event V: Active transcription, rapid cell growth, and replication of mitochondria.

Which of the following options correctly represents a continuous, chronological sequence of these events as the cell progresses through a complete cell cycle?
