The correct Answer is:
To determine which statements are correct regarding the cell cycle, let's analyze each statement one by one: ### Step 1: Analyze Statement I **Statement I:** At G0 stage, the cell remains metabolically active. - **Explanation:** The G0 phase is a resting state where the cell is not actively preparing to divide. However, cells in G0 can still be metabolically active, performing functions necessary for survival. - **Conclusion:** This statement is **correct**. ### Step 2: Analyze Statement II **Statement II:** In G2 phase, proteins are synthesized. - **Explanation:** The G2 phase is the final phase of interphase where the cell prepares for mitosis. During this phase, the cell synthesizes proteins and organelles needed for cell division. - **Conclusion:** This statement is **correct**. ### Step 3: Analyze Statement III **Statement III:** In animal cells during S phase, duplication of centrioles occurs in the cytoplasm. - **Explanation:** The S phase (Synthesis phase) is when DNA replication occurs. In animal cells, centriole duplication also takes place during this phase, which is crucial for proper cell division. - **Conclusion:** This statement is **correct**. ### Step 4: Analyze Statement IV **Statement IV:** During the cell cycle, most of the time the cell remains in interphase. - **Explanation:** The cell cycle consists of interphase (G1, S, G2) and the mitotic phase (M). Interphase is indeed the longest phase of the cell cycle, where the cell spends the majority of its time. - **Conclusion:** This statement is **correct**. ### Final Conclusion All four statements (I, II, III, and IV) are correct. Therefore, the correct answer is that all statements are true.
