Explanation:

The cell cycle has distinct phases: G₁ is for cell growth, S phase is dedicated to synthesizing (replicating) DNA to double the cell's genetic material, G₂ is for final growth and preparation for division, G₀ is a resting non-dividing state, and mitosis is the phase of nuclear division. DNA replication occurs specifically in the S (synthesis) phase.
