Quick Summary

Interphase is the period in the cell cycle that occurs between cell divisions. It is composed of three stages: gap 1 (G1), synthesis (S), and gap 2 (G2). During interphase, the cell grows, copies its DNA, and prepares for division. The S phase, specifically, is when DNA replication takes place. Cells have checkpoints to ensure the cell cycle progresses correctly, assessing DNA for damage before and after the S phase. If abnormalities are detected, the cell may undergo programmed cell death (apoptosis). However, defects in these processes can lead to uncontrolled cell growth, a characteristic of cancer.12
