The initiation of condensation of chromosomal material marks the beginning of
1. S phase
2. Prophase
3. G1
4. G2
Chromosomal material becomes ……… in the process of chromatin condensation.
| 1. | Untangled |
| 2. | Tangled |
| 3. | Interwined |
| 4. | Hellicoid |
The duplication in S phase and has started moving towards opposite poles in Prophase, we are talking about which cell component ?

2. Microbodies
3. Centriole
4. Nuclear envelope
Asters are not
| 1. | Microtubules |
| 2. | Radiate out from centrosomes |
| 3. | Present on both the poles |
| 4. | Intermediate filament |
Mitotic Apparatus
| 1. | Two asters |
| 2. | Spindle Fibres |

Condensation of chromosomes is completed and chromosomes are spread throughout cytoplasm, here we are talking about which phase of cell cycle?
| 1. | Prophase |
| 2. | Interphase |
| 3. | Metaphase |
