Which phase of the cell cycle is primarily about cell growth and carrying out normal functions?

• A. Prophase
• B. Metaphase
• C. Anaphase
• D. Interphase

Answer: (D)

Growth and everyday cellular activities happen during interphase. In this stretch of the cycle the cell enlarges, makes more proteins and organelles, and carries out metabolism while preparing for division. DNA is copied as needed so the cell can split its genetic material later. The other stages—where chromosome pairs condense, line up, and are pulled apart—are focused on dividing the genetic material rather than performing normal functions, so they’re not about growth and routine activity. So, the phase that mainly handles growth and normal functioning is interphase.
