Mitosis is also called ‘equational division’ because:
| 1. | the number of chromosomes in both daughter cells are the same |
| 2. | the sum of the number of chromosomes in two daughter cells is equal to the number of chromosomes in the parent cell |
| 3. | each progeny cell receives only one set of chromosomes from the parent cell |
| 4. | the number of chromosomes in the parent and the progeny cells is the same |

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
