    Study Notes

    Cell Reproduction

    • Cell cycle stages: Interphase (G1, S, G2) are growth stages.
    • G1: cell growth
    • S: DNA synthesis (DNA is replicated)
    • G2: more growth, organelles duplicated
    • Mitosis: cell division.
    • Prophase: chromosomes condense, nuclear membrane dissolves.
    • Metaphase: chromosomes line up in the middle.
    • Anaphase: sister chromatids separate.
    • Telophase: chromosomes reach opposite poles and nuclear envelopes form.
    • Cytokinesis: cytoplasm divides.

    Mitosis Diagrams

    • Diagrams show the stages of mitosis with labeled examples.

    Cell Cycle Activity
