Questions and Answers

What is the main nuclear change that occurs during apoptosis?

  • Nuclear enlargement
  • Increased organelle production
  • Chromatin condensation and DNA fragmentation (correct)
  • Cytoplasmic swelling

    • Which of the following is NOT a characteristic of apoptosis?

  • Swelling and bursting of the cell (correct)
  • Chromatin condensation
  • Phagocytosis of extruded apoptotic bodies
  • Formation of apoptotic bodies

    • What is the primary difference between apoptosis and necrosis?

  • Apoptosis is an active process requiring energy, while necrosis is passive (correct)
  • Apoptosis affects large areas, while necrosis affects individual cells
  • Apoptosis always leads to inflammation, while necrosis does not
