Question
Colchicine is a chemical that stops chromatids from separating during mitosis. Which phase will the cell reach and then stop dividing?
Correct Answer
Option A is the correct answer.
Detailed Explanation
Chromatids separate and move to opposite poles during anaphase. If colchicine prevents their separation, the cell will progress through metaphase (where chromosomes align) but will be unable to complete anaphase and will therefore stop dividing at that point.
Hint
In which phase do sister chromatids actually pull apart?
