1. The Cell Cycle Cells undergoing changes due to the cell cycle
2. Introduction The cell cycle consists of two parts: Interphase The mitotic phase (mitosis) A cell in interphase – G1
3. Interphase This is a time when it just performs its function normally Made up of three periods: G1: the cell grows S: duplication of the cell’s DNA occurs G2: the cell prepares to divide The cell cycle in a pie chart
