Consider the following four statements (l-lV) related to cell cycle, and select the correct option stating them as true [T] and false [F].
| I | Cell growth in terms of cytoplasmic increase is a continuous process. |
| II | Interphase is the phase of actual cell division. |
| III | The number of chromosomes doubles in S-phase |
| IV | The cells that do not divide further exit G 1 -phase to enter the G0 stage. |
Options:

| Statement I: | In mitosis, chromosomal number in the progeny as well as in parents remains the same |
| Statement II: | Mitosis takes place in gametes |
| 1. | Both statement I and statement II are correct |
| 2. | Both statement I and statement II are incorrect |
| 3. | Statement I is correct but statement II is incorrect |
| 4. | Statement I is incorrect but statement II is correct |
| Assertion(A): | Cell division, DNA replication, and cell growth have to take place in a coordinated way. |
| Reason(R): | This well coordinated way ensures correct division and formation of progeny cells containing intact genomes. |
Choices for Assertions and reasons:
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are True, but (R) is not the correct explanation of (A). |
| 3. | (A) is True, but (R) is False. |
| 4. | (A) is False, but (R) is True. |
