• fourth step

  Anaphase

  
• fifth step?

  Telophase

  
• last (sixth) step?

  Cytokinesis

  
• What is produced in mitosis?

  -The cell divides to produce two daughter cell

  -Daughter cells are genetically identical
• What is the phase of the cell cycle where DNA replicates?


  Interphase
• How does DNA replicate during interphase?

  By semi-conservative replication
• What is visible in the nucleus during interphase?

  The nucleus is visible
• What is the state of chromosomes during interphase?

  Chromosomes are not visible
• What percentage of the cell cycle is interphase?

  95%
• What happens to chromosomes during prophase?

  Chromosomes condense and become visible
• What are chromosomes made up of during prophase?

  Two sister chromatids joined at the centromere
• How are the sister chromatids during prophase?

  They are identical
• What happens to the nuclear membrane during prophase?

  It breaks down
• Where do centrioles move during prophase?

  To opposite poles
• What occurs during metaphase?

  Chromosomes line up at the equator
• What attaches centromeres to spindle fibers during metaphase?

  Spindle fibers attached to centrioles
• What happens during anaphase?

  The chromatids are pulled apart
• What occurs during telophase?

  Chromatids reach the poles
• What happens to DNA during telophase?

  DNA uncoils
• What happens to spindle fibers during telophase?

  They break down
• What reforms during telophase?

  The nuclear membrane reforms
• What reappears during telophase?

  The nucleolus reappears
• What is cytokinesis?

  The cell divides to form two cells
• How does cytokinesis occur in animals?

  By forming a cleavage furrow
• How does cytokinesis occur in plants?

  By forming a cell plate
• What are centrioles?

  Cylindrical organelles involved in cell division
• What is the function of centrioles?

  They are involved in cell division
• What are spindle fibers?

  String-like filaments involved in cell division
• What do spindle fibers attach to during cell division?


  They attach to the centrioles
