Microtubules play a role in the migration of chromosomes to opposite ends of a dividing cell during anaphase. (Ans. D)
Explanation:
In mitosis after the metaphase stage, anaphase stage occurs where replicated chromosomes are divide and the copied chromosomes migrate to the opposite poles of the cell.
In anaphase stage two phases are occurs:
Anaphase A: In this phase chromosome moves to pole of a dividing cell, this movement is produced by the action occurs in kinetochores and a subclass present in microtubules present in kinetochores are known as kinetochore microtubules.
Anaphase B: In this phase separation of dividing cell poles from each other is occurred. This movement is produced by the action of inter-polar microtubules and astral microtubules.
It would be B) unconscious. I know this because when you're not thinking about something it is not in your conscious mind, so it would be in your unconscious mind.
