What is the phase of the cell cycle where the cell grows and prepares for mitosis?

In the cell cycle, the phase where the cell primarily grows and prepares for mitosis is known as the G2 phase. During this phase, which follows the S phase where DNA replication occurs, the cell continues to grow and produces the proteins and organelles necessary for mitosis. It acts as a checkpoint to ensure that all the DNA has been replicated correctly and that the cell has the resources needed to divide.

While the G1 phase is a period of growth and synthesis of various molecules, it occurs before DNA replication. The M phase is specifically when mitosis occurs, and the S phase is dedicated to DNA synthesis. Therefore, the G2 phase is the correct answer as it encapsulates the preparation for the actual process of mitosis, ensuring the cell is fully equipped for successful division.
