In animal cells, during the S phase:
I: | DNA replication begins in the cytoplasm |
II: | The centriole duplicates in the nucleus |
1. Only I is correct
2. Only II is correct
3. Both I and II are correct
4. Both I and II are incorrect
Consider the two statements:
Statement I: | Mitosis helps in restoration of nuclear cytoplasmic ratio for effective working of a cell. |
Statement II: | Mitosis leads to formation of genetically diverse cells leading to generation of variations. |
1. | Statement I is correct; Statement II is incorrect |
2. | Statement I is correct; Statement II is correct |
3. | Statement II is incorrect; Statement I is correct |
4. | Statement I is incorrect; Statement II is incorrect |
I: | Terminalisation of chiasmata takes place. |
II: | Meiotic spindle is assembled. |
III: | Nucleolus disappears and the nuclear membrane breaks down. |
