The period in which the major reorganization of virtually all components of the cell occurs
1. Prophase
2. M phase
3. S phase
4. G1 phase
Cell division
1. | Progressive process |
2. | A very clear cut lines cannot be drawn between various phases |
3. | Both 1 and 2 |
4. | Clear cut demarcation between all phases |
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 ?
1. DNA
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
3. Centrosomes
4. Both 1 and 2
Which of the following cellular components can be seen at the end of Prophase?
1. | Golgi Bodies |
2. | ER |
3. | Nucleolus |
4. | Compact mitotic chromosomes |
The complete disintegration of the nuclear envelope marks the
1. | Ending of the second phase(stage) of mitosis |
2. | Start of the second phase(stage) of mitosis |
3. | Metaphase |
4. | Both B and C |
Condensation of chromosomes is completed and chromosomes are spread throughout cytoplasm, here we are talking about which phase of cell cycle?
