What occurs during the G2 phase of the cell cycle?

During the G2 phase of the cell cycle, the cell undergoes a period of preparation for mitosis. This phase occurs after DNA replication has been completed in the S phase, and its primary focus is on ensuring that the cell is fully prepared to divide.

During G2, the cell continues to grow and produce the necessary organelles and proteins required for cell division. This includes synthesis of microtubules that will form the spindle apparatus, as well as other components that ensure the division process goes smoothly. The G2 phase also involves the cell checking for DNA damage and repairing any issues before entering mitosis, ensuring that each daughter cell will receive a complete set of genetic material.

While cell growth and organelle production occur in other phases of the cell cycle, the distinctive feature of the G2 phase is the extensive preparation and assembly of structures that will be utilized in the upcoming mitotic processes. Thus, identifying the production of organelles specifically needed for cell division as a defining characteristic of the G2 phase is accurate.
