The G2 phase is best described as?

The G2 phase is best described as?

• A. The phase of mitosis
• B. The phase following cytokinesis
• C. The phase following DNA synthesis where the cell prepares for mitosis
• D. The phase during which the cell rests in G0

Answer: (C)

G2 is the second gap period in the cell cycle, the stage after DNA has been replicated and before the cell actually divides. During this time the cell grows a bit more, duplicates organelles, and makes sure the copied DNA is intact and free of damage so everything is ready for mitosis. It also produces proteins needed to form the mitotic spindle, which will guide chromosome separation when division begins. Because the cell is preparing for mitosis, this is best described as the phase after DNA synthesis where preparation for mitosis occurs. It’s not the stage of mitosis itself, nor the finishing steps of cytokinesis, and it isn’t a resting state like G0, where cells are not actively preparing to divide.
