Which of the following statements regarding the cell cycle is/are corr...
- Statement i is incorrect because DNA replication only occurs during a specific stage of the cell cycle (S phase), not continuously throughout the cycle.
- Statement ii is correct as the cell cycle includes phases (G1, S, G2, and M) that collectively lead to cell division.
- Statement iii is correct since cell growth (cytoplasmic increase) does happen continuously throughout the cell cycle.
- Statement iv is incorrect because the distribution of replicated chromosomes to daughter nuclei involves complex events, particularly during mitosis.
Thus, the correct statements are ii and iii, making Option A the correct answer.
Line in NCERT: "Although cell growth (in terms of cytoplasmic increase) is a continuous process, DNA synthesis occurs only during one specific stage in the cell cycle."

Which of the following statements regarding the cell cycle is/are corr...
Understanding the Cell Cycle
The cell cycle is a series of stages that a cell goes through leading to its division. Let's analyze the statements provided:
i. DNA replication occurs continuously throughout the cell cycle.
- This statement is incorrect. DNA replication specifically occurs during the S phase (Synthesis phase) of interphase, not continuously throughout the entire cell cycle.
ii. The cell cycle consists of a series of stages that lead to the division of a cell into two daughter cells.
- This statement is correct. The cell cycle includes stages such as G1, S, G2, and M phase, which culminate in cell division (mitosis).
iii. Cell growth in terms of cytoplasmic increase is a continuous process.
- This statement is also correct. Cell growth does occur continuously as cells prepare for division, with gradual increases in cytoplasmic volume.
iv. The distribution of replicated chromosomes to daughter nuclei is a simple and straightforward event.
- This statement is misleading. The distribution of chromosomes during mitosis is a complex process involving several checkpoints and mechanisms to ensure accuracy.
Conclusion
Based on the evaluations:
- Correct Statements: ii and iii
- Incorrect Statements: i and iv
Thus, the correct answer is option a) ii and iii. The cell cycle is indeed a structured series of stages leading to division, with continuous growth occurring, while DNA replication is not continuous and chromosome distribution is complex.
