Based on the data, which of the following best describes the relationship between the G2 phase and the mitotic spindle formation?

A.D) Mitotic spindle formation occurs after the G2 phase

B.A) The G2 phase begins with mitotic spindle formation

C.B) The G2 phase ends with mitotic spindle formation

D.C) Mitotic spindle formation occurs during the G2 phase

Explanation

Core Concept

The G2 phase is the final stage of the cell cycle, during which the cell prepares for mitosis by replicating its DNA and organizing its chromosomes. Mitotic spindle formation occurs towards the end of the G2 phase, as the cell begins to divide. Options A and C are incorrect because mitotic spindle formation does not begin during the G2 phase. Option D is incorrect because mitotic spindle formation occurs before the mitotic phase, not after the G2 phase.

Correct Answer

B) The G2 phase ends with mitotic spindle formation
