Here's a breakdown of the cell cycle phases and what happens in each:

* G1 phase (First Gap): The cell grows and performs its normal functions.

* S phase (Synthesis): DNA is replicated, creating two identical copies of each chromosome.

* G2 phase (Second Gap): The cell continues to grow and prepares for mitosis.

* M phase (Mitosis): The duplicated chromosomes are separated and distributed into two new daughter cells.
