  1. 1. Mitosis <ul><li>By Joey Cord </li></ul><ul><li>Period 4 </li></ul><ul><li>March 26 th , 2009 </li></ul>
  2. 2. Definition <ul><li>– Noun T he usual method of cell division, characterized typically by the resolving of the chromatin of the nucleus into a threadlike form, which condenses into chromosomes, each of which separates longitudinally into two parts, one part of each chromosome being retained in each of two new cells resulting from the original cell. </li></ul><ul><li>Definition from http://dictionary.reference.com/browse/mitosis </li></ul>
  3. 3. Chromosomes <ul><li>In the mitosis process, the nucleus and the genetic information in the nucleus (Chromosomes) duplicate, or make a copy of themselves. After this occurs, the chromosomes are “pulled” apart and two identical cells are made. This Process is illustrated below. </li></ul>
  4. 4. The Nucleus <ul><li>In biology, the nucleus is often referred to as “The Control Center” of the cell. That is because the nucleus controls the cells function and reproduction. It also contains the genetic material of the cell. This material is organized into multiple long linear DNA molecules in complex with a large variety of proteins, such as histones, to form Chromosomes. </li></ul>
  5. 5. The Steps Of Mitosis
  6. 6. Interphase The Phase in which the cell prepares for division.
  7. 7. Prophase At the onset of prophase, chromatin condenses together into a highly ordered structure called a chromosome.
  8. 8. Prometaphase The nuclear envelope disassembles and microtubules invade the nuclear space. This is called open mitosis, and it occurs in most multicellular organisms
  9. 9. Metaphase The centromeres of the chromosomes convene themselves on the metaphase plate, an imaginary line that is equidistant from the two centrosome poles.
  10. 10. Anaphase Anaphase begins abruptly with the regulated triggering of the metaphase-to-anaphase transition. At this point the Anaphase becomes activated. This terminate activity by cleaving and inactivating the M-phase cyclin required for the function of M-phase cyclin dependent kinases (M-Cdks). It also cleaves securin , a protein that inhibits the protease known as separase . Separase then cleaves cohesin , a protein responsible for holding sister chromatids together
  11. 11. Telophase Telophase (sometimes spelled telephase ), from the ancient Greek &quot;τελος&quot; (end) and &quot;φασις&quot; (stage), is a stage in either meiosis or mitosis in a eukaryotic cell reversing the effects of prophase and prometaphase events. Information gathered from http://en.wikipedia.org/wiki/Telophase
