You're describing the cell cycle, specifically the G1 phase (also known as the first gap phase) where a cell grows and carries out its normal metabolic functions. Here's a breakdown:

* G1 phase: This is the first phase of the cell cycle. The cell grows in size, synthesizes proteins and other molecules, and prepares for DNA replication.

* S phase (Synthesis phase): During this phase, the cell's DNA is replicated.

* G2 phase (Second gap phase): The cell continues to grow and synthesize proteins, ensuring it has all the necessary components for cell division.

* M phase (Mitosis): This is the actual cell division phase, where the nucleus and cytoplasm divide, resulting in two daughter cells.

Key takeaways:

* Cell growth and metabolism occur primarily during the G1 phase.

* DNA replication occurs in the S phase.

* The cell continues to grow and prepare for division in the G2 phase.

* Cell division occurs in the M phase.
