Consider the two statements:
| Statement I: | The interphase represents the phase between two successive M phases and DNA replication takes place in the interphase. |
| Statement II: | The stage between the two meiotic divisions is called interkinesis and there is no replication of DNA during interkinesis. |
| 1. | Statement I is correct; Statement II is correct |
| 2. | Statement I is correct; Statement II is incorrect |
| 3. | Statement I is incorrect; Statement II is correct |
