What role do microtubules play during mitosis?
a. microtubules line up chromosomes at the equator of the cell during metaphase
b. microtubules play a role in the disassemble and reassembly of the nuclear membrane
c. microtubules play a role in the formation of the cell plate when plant cells undergo cell division
d. microtubules play a role in the migration of chromosomes to opposite ends of a dividing cell during anaphase

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.
