Summary Introduction
Introduction: Cell division is a natural process in which a parent cell divides to produce two daughter cells. Cell cycle is divided into interphase and mitosis. Interphase is divided into gap1 (G1) phase, synthetic phase (S-phase), and gap 2 (G2) phase. Mitosis phase is divided into prophase, metaphase, anaphase, and telophase.
