Interphase
Interphase
The stage in the cell cycle where the cell grows, replicates its DNA, and prepares for division.
G₁ Phase
G₁ Phase
The first stage of interphase where the cell grows and produces proteins for normal cell functions.
S Phase
S Phase
The stage of interphase where DNA replication occurs, creating two identical copies of the cell's DNA.

Study Notes
Interphase Stages
- Interphase consists of three stages: G1, S, and G2
- G1: In this phase, the cell produces proteins that are essential for cell growth and preparing for DNA replication.
- S: During the synthesis phase, DNA replication occurs.
- G2: In this phase, the cell produces proteins needed for further cell growth and prepares for cell division. DNA is checked and repaired.
Cell Cycle Stage
- Cells that do not divide are in the G0 phase.
