What occurs during the G2 phase of interphase?

During the G2 phase of interphase, cells undergo significant growth and preparation for cell division. This phase follows DNA synthesis, which occurs in the S phase. During G2, the cell continues to grow by producing more proteins and organelles, and it prepares the necessary components for mitosis. This includes the replication of centrosomes and the synthesis of proteins that are essential for the formation of the mitotic spindle, which will help in the separation of chromosomes during division.

In this phase, the cell also performs checks to ensure that DNA has been accurately replicated without damage. If errors or damage are detected, the cell may initiate repair mechanisms to correct these issues before proceeding to mitosis. The primary focus during the G2 phase is on preparing the cell for a successful division, ensuring that the daughter cells are ready to inherit the correct genetic material and cellular machinery necessary for their function.
