Question 2:

Which of the following is not a phase of mitosis?

Explanation: Interphase is not a phase of mitosis. Interphase is the phase between two successive mitotic divisions and includes the G1, S, and G2 phases. Therefore, option B is correct.

Question 3:

What is the correct sequence of phases in mitosis?

Explanation: The correct sequence of phases in mitosis is Prophase, Metaphase, Anaphase, and Telophase. Therefore, option A is correct.

Question 4:

During which phase of the cell cycle do the chromosomes align at the equator of the cell?

Explanation: The alignment of chromosomes at the equator of the cell occurs during the Metaphase of mitosis. Therefore, option A is correct.

Question 5:

What is the division of the cytoplasm called after the completion of mitosis?
