WebThe cell cycle is made up of two main stages: interphase and mitosis. During interphase, cells are duplicating their material and synthesising proteins to prepare to divide. Interphase encompasses 3 phases: G1, S and G2. During S phase, DNA is replicated. Mitosis encompasses prophase, prometaphase, metaphase, anaphase telophase.
