The correct Answer is:
To analyze the statements provided in the question, we will evaluate each statement one by one. ### Step-by-Step Solution: 1. **Statement I: `G_(0)` state of cell denotes exit of cell from cell cycle.** - The G0 phase is indeed a resting or quiescent phase where the cell is not actively dividing and has exited the cell cycle. This statement is **True**. 2. **Statement II: The two chromatids of a metaphase chromosome represent replicated chromosome to be separated at anaphase.** - During metaphase, chromosomes are aligned at the cell's equatorial plane, and each chromosome consists of two sister chromatids that are identical. These chromatids are indeed separated during anaphase. This statement is **True**. 3. **Statement III: DNA polymerase is active in S-phase.** - The S-phase (Synthesis phase) is when DNA replication occurs, and DNA polymerase is the enzyme responsible for synthesizing new DNA strands. Therefore, this statement is **True**. 4. **Statement IV: RNA polymerase is active throughout Interphase.** - RNA polymerase is responsible for synthesizing RNA from DNA. It is active during all phases of interphase (G1, S, and G2) to transcribe genes necessary for cell function and preparation for division. This statement is **True**. ### Conclusion: All four statements (I, II, III, and IV) are **True**.
