The cell cycle and cell division

• What are the main phases of the cell cycle?

  Interphase and mitosis
• What happens during cell interphase?

  Each chromosome is copied and sub-cellular structures are copied
• What occurs during mitosis?

  Chromosome copies line up along the middle of the cell and the nucleus divides
• What is the definition of the cell cycle?

  The process by which cells divide, involving a specific set of phases
• What is mitosis?

  A type of cell division that produces genetically identical cells
• What is the nucleus?

  A sub-cellular structure that contains the genetic material (DNA) and controls cell activities
• What are chromosomes?

  Tightly coiled strands of DNA that carry genetic material
• What sub-cellular structure holds the genetic material in an animal cell?

  Nucleus
• What structures are formed when DNA is wound up tightly?

  Chromosomes
• What are the definitions of key terms related to the cell cycle?

  • Cell cycle: A series of phases a cell undergoes to divide
  • Cytoplasm: A jelly-like liquid where many chemical reactions occur
  • Cell membrane: Surrounds the cell and controls what can enter and exit it
• What type of cell division produces genetically identical cells?

  Mitosis
• What happens during cell growth in the cell cycle?

  DNA and sub-cellular structures are copied
• What is the order of stages during the cell cycle?

  1. Cell growth
  2. Mitosis: nuclear division
  3. Division of cell membrane and cytoplasm
• What occurs during the second stage of the cell cycle?

  Chromosomes line up along the middle of the cell and the nucleus begins to divide
• What are the true statements about the cell cycle?

  Two genetically identical daughter cells are produced and after cell growth, the cell has twice the amount of DNA
• Mitosis consists of four stages: prophase, metaphase, anaphase, and telophase.
