The start of the second phase of mitosis, metaphase, is marked by:
| 1. | complete disintegration of the nuclear envelope |
| 2. | alignment of chromosomes at the equatorial plate |
| 3. | de-condensation of chromatin |
| 4. | reappearance of the nucleolus |

Consider the given two statements:
| I: | Morphology of chromosomes is best studied at metaphase |
| II: | At this stage, a chromosome is made up of two sister chromatids, held together at the centromere |
1. Both I and II are True and II explains I
2. Both I and II are True but II does not explain I
3. I is True but II is False
4. I is False but II is True

Hints
Identify the incorrect statement regarding cytokinesis:
| 1. | Animal cells divide by cleavage furrow |
| 2. | Cell plate formation takes place during cytokinesis in plant cells |
| 3. | The cell wall formation in plant cells starts near the existing lateral walls and grows inwards |
| 4. | At cytokinesis, mitochondria and plastids are distributed between daughter cells |

Hints
At the metaphase plate:
| 1. | The sister chromatids of a chromosome are connected by their kinetochores to the spindle fibers from the same pole |
| 2. | The non sister chromatids of a chromosome are connected by their kinetochores to the spindle fibers from the same pole |
| 3. | The sister chromatids of a chromosome are connected by their kinetochores to the spindle fibers from the opposite poles |
| 4. | The non sister chromatids of a chromosome are connected by their kinetochores to the spindle fibers from the opposite poles |
