Question: A cell attempts mitosis with only one spindle pole (with many microtubules), but is otherwise normal. Which of the following is true for this cell?
The spindle would never attach to kinetochores.
If the drug Taxol were administered, the spindle would be unaffected.
The cell would begin but not complete telophase.
The cell would not be able to enter anaphase.
Question: Which of the following events occur after the nuclear envelope dissolves?
Check all that apply:
DNA condenses into chromosomes.
Chromosomes align at the midline of the cell.
Cohesin dissolves.
Sister chromatids move to opposite sides of the cell.
Question: Which of the following are made of or contain DNA?
Check all that apply:
Chromosomes
Cohesin
Kinetochores
Microtubules
Question: Which of the following is a microtubule organizing center?
Chromosome
Centrosome
Centromere
None of these
Question: How does the spindle move sister chromatids during anaphase?
Sister chromatids are pushed together, away from spindle poles.
Sister chromatids are pulled toward the spindle poles.
Spindle microtubules engage in a tug-of-war that centers chromosomes at the midline.
None of the above. Spindles do not use mechanical forces.
