Destruction of both centrosomes with a laser beam in an animal cell:
1. | will prevent both mitosis and cytokinesis |
2. | prevents cytokinesis even if mitosis has been completed normally |
3. | permits cytokinesis but the daughter cells fail to enter a new S phase |
4. | prevents mitosis but permits cytokinesis |
Anaphase is characterized by two distinct motions. The second motion, anaphase B:
1. | moves chromosomes to either pole of a dividing cell and this movement is primarily generated by the action of kinetochore microtubules. |
2. | moves chromosomes to either pole of a dividing cell and this movement is primarily generated by the action of interpolar microtubules. |
3. | involves the separation of the two poles from each other and the movement for this is primarily generated by the action of kinetochore microtubules. |
4. | involves the separation of the two poles from each other and the movement for this is primarily generated by the action of interpolar microtubules. |
