Cell division involves several key steps, primarily focusing on the duplication and segregation of genetic material and cellular components. 1. Interphase: This is the preparatory phase where the cell grows, duplicates its DNA (replication), and synthesizes proteins and organelles. It consists of G₁, S, and G₂ subphases. 2. Mitosis (for somatic cells) or Meiosis (for gametes): This is the division of the nucleus. Prophase*: Chromosomes condense and become visible. The nuclear envelope breaks down, and the spindle fibers begin to form. Metaphase*: Chromosomes align at the center of the cell (metaphase plate). Anaphase*: Sister chromatids (identical copies of a chromosome) separate and move to opposite poles of the cell. Telophase*: Chromosomes decondense, and new nuclear envelopes form around the two sets of chromosomes. 3. Cytokinesis: This is the division of the cytoplasm, which typically overlaps with telophase. The cell physically splits into two daughter cells. In animal cells, a cleavage furrow forms; in plant cells, a cell plate forms.
