Which statement about Interphase is true?

• A. DNA replication occurs during Interphase
• B. Chromosome condensation occurs
• C. The cell spends most of its time in G1,S,G2
• D. Spindle apparatus forms during Interphase

Answer: (C)

The key idea is understanding how the cell cycle is organized and where most time is spent. Interphase includes three stages—G1 (growth), S (DNA replication), and G2 (preparation for mitosis). The cell spends the majority of its cycle in this phase, with mitosis occupying only a relatively brief period. That makes the statement about spending most of the time in G1, S, and G2 the best summary of Interphase.

DNA replication does happen during the S phase, which is within Interphase, so that event occurs during this period as well. However, the question is about what is true about Interphase as a whole, and the most informative statement is that most of the cell’s time is spent in those three phases before mitosis.

Chromosome condensation occurs during mitosis (prophase), not during Interphase, and the spindle apparatus forms during mitosis as well. These facts align with why those options aren’t true descriptions of Interphase.
