Module 10: Mitosis

• Mitosis process where a single cell divided into two identical daughter cell

  •somatic cell
• Prophase cell starts to break down some structures and build others up

  •setting the stage for division of the chromosome
• Prophase 3 major events

  1. Chromosomes condense
  2. Spindle fibers form
  3. Chromosomes are captured by spindle
• Metaphase mitotic spindle has captured all the chromosomes and lined up at the middle of the cell (metaphase plate) ready to divide
• Anaphase sister chromatids separate from each other and are pulled towards the opposite ends of the cell
• Telophase cell is nearly dividing

  •starts to re establish its normal structure as cytokinesis takes place

  •It unpackd chromosome and formation of new nuclear envelope
• Animal cell called cleavage forrow

  Plant is cell plate
• Centromere a constricted region of a chromosome and plays a key role in helping the cell divide up its DNA during division

  •Serving as the cohesion between sister chromatids
• Interphase a non dividing state or preparation the cell divison
• Cell division an inegral part of the cell cycle. Cell divides to give rise to new ones, to replace those old and injured cells and promote growth of organisms
• Cell cycle an orderly sequence of events that describes the stages of a cells life from the division of a single parent cell to the production of two new daughter cells
