The Cell Cycle

• What happens in interphase?


  Cell gets bigger. DNA replicates. Protein synthesis occurs. Organelles are synthesised.
• What happens in prophase?


  Chromosomes become visible. Nuclear envelope disintegrates. Nucleolus disappears.
• What happens in metaphase?


  Spindle is formed & chromatids attach to it. Sister chromatids move to equator of the cell
• What happens in anaphase?


  Sister chromatids pulled to opposite poles of the cell as the spindle fibres contract.
• What happens in telaphase?


  Nuclear envelope reforms. Spindle disintegrates. Cytoplasm splits. Two daughter cells are created.
• What does the cell cycle produce?


  Two identical daughter cells
• In which phase does mitosis officially start?


  Prophase
• What does mitosis make new cells for?

  Growth

  To repair tissue
