What Is the Cell Cycle? Definition and Significance The cell cycle is a series of events that cells go through to grow and divide. It ensures that genetic material is accurately replicated and distributed, enabling organisms to develop, repair tissues, and maintain homeostasis. The cell cycle is fundamental to all multicellular life forms and is tightly regulated to prevent abnormal growth, such as cancer. Phases of the Cell Cycle Interphase: The longest phase, during which the cell prepares for division by growing and copying its DNA. It comprises three sub-phases: G1 phase (First Gap): Cell growth and normal functions S phase (Synthesis): DNA replication G2 phase (Second Gap): Preparing for mitosis Mitosis (M phase): The process of nuclear division, resulting in two genetically identical daughter cells. It includes stages: Prophase Metaphase Anaphase Telophase Cytokinesis: The division of the cytoplasm, culminating in two separate cells. 2 Introduction to Pogil Activities and Their Role in Learning What Is Pogil?
