Cell division, cell diversity and cellular oragnisation

• What is the cell cycle?


  A regulated cycle of division with intermediate growth periods
• What are the stages of the cell cycle?

  1. Interphase
  2. Mitosis or meiosis (nuclear division)
  3. Cytokinesis (cytoplasmic division)
• What happens during interphase?

  It consists of G1, S, and G2 phases where the cell prepares for division
• What occurs during the G1 phase of interphase?

  • Cell synthesizes proteins for replication (e.g., tubulin for spindle fibers)
  • Cell size doubles
