Q. No.Identify the stage of mitosis shown in the given diagram:
1. Prophase
2. Metaphase
3. Anaphase
4. Telophase
| 1. Prophase | 2. Metaphase |
| 3. Anaphase | 4. Telophase |
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
If a cell had 4[2 pairs] chromosomes at G1 phase, what would be the number of chromosomes in this cell at the end of anaphase?
| 1. | 2 | 2. | 4 |
| 3. | 6 | 4. | 8 |
All the following key events take place during telophase of mitosis except:
1. Chromosomes cluster at the opposite spindle poles
2. Chromosomes become discrete
3. Nuclear envelope reforms
4. Nucleolus, ER and Golgi complex reform
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 |
Liquid endosperm in coconut forms due to:
1. Failure of cytokinesis after karyokinesis
2. Failure of karyokinesis before cytokinesis
3. Disruption of spindle fibers at metaphase
4. Continued DNA replication during cytokinesis
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 |
The Mitotic phase of a typical eukaryotic cell is divided into:
| 1. | Two stages | 2. | Three stages |
| 3. | Four stages | 4. | Five stages |
