The correct Answer is:
To determine which events do not occur during the interphase stage of the cell cycle, let's analyze each option provided: 1. **RNA and Protein Synthesis (Option A)**: - During interphase, the cell is actively preparing for division. This includes synthesizing RNA and proteins necessary for cell function and growth. Therefore, this event does occur in interphase. 2. **Cytoplasmic Growth (Option B)**: - Interphase is characterized by cell growth, which includes an increase in cytoplasmic volume. Thus, cytoplasmic growth is an event that occurs during interphase. 3. **Polymerization of Spindle Fibres Protein (Option C)**: - The polymerization of spindle fibers occurs during the mitotic phase (specifically in prophase) when the cell is preparing to divide. This event does not occur during interphase. 4. **Disappearance of Golgi Bodies (Option D)**: - The Golgi apparatus does not disappear during interphase; it may undergo some changes but does not completely disappear until the cell enters mitosis. Thus, this event does not occur in interphase. 5. **DNA Molecules in Highly Supercoiled Stage (Option E)**: - During interphase, DNA is in a less condensed form (chromatin) to allow for transcription and replication. It only becomes highly supercoiled during mitosis. Therefore, this event does not occur in interphase. Based on this analysis, the events that do not occur in the interphase stage of the cell cycle are: - **C. Polymerization of Spindle Fibres Protein** - **D. Disappearance of Golgi Bodies** - **E. DNA Molecules in Highly Supercoiled Stage** ### Final Answer: The events that do not occur in interphase are **C, D, and E**.
