  1. Mitosis – The replication of the nucleus. There are 6 stages: 0 – I 1 – Poured 2 – Milk 3 – At 4 – Tom 5 – Cat This is an asexual process!

  2. Interphase 0 - Interphase is not part of mitosis but is included here as a reminder that interphase precedes mitosis. (Hence, it has the number 0.) Chromatin is material in a cell nucleus consisting of DNA and protein. Chromatids are “unzipped” & copied “l” = Chromatid (DNA) “X” = Chromosome (Copied DNA)

  3. Prophase 1. Prophase - In prophase, the nucleolus disappears . Chromosomes are “rod-like” Look like “X’s” The centrosomes are pushed to opposite "poles" (extremes) of the cell. Eventually, the spindle extends between two opposite poles of the cell.

  4. Metaphase 2. Metaphase Metaphase is characterized by the "metaphase plate". This is a mid-point region within the cell that is formed by the chromatid pairs aligning along the center of the miotic spindle. Chromosomes line up in the middle of the cell.

  5. Anaphase 3. Anaphase The centromeres split separating the two members of each chromatid pair - which then move to the opposite poles of the cell: When they are separated the chromatids are called chromosomes. As the chromosomes are pulled, they appear to be "V"-shaped because the centromeres lead the way, dragging the trailing arms of the chromosomes towards the poles. Chromosomes are split into identical chromatids 1 chromatid from each chromosome moves to an opposite side of the cell Chromatids look like “<” and “>”

  6. Telophase 4. Telophase Telophase begins after the chromosomal movement stops. Cells are beginning to split.

  7. Cytokinesis 5. Cytokinesis - During Cytokinesis, the cytoplasm (the liquid center of the cell that holds the organelles into place.) splits into two equal halves, two separate & identical cells. A new and complete nucleus forms in each of the two cells.

  8. Interphase 0 -interphase - The cycle is about to start again ... Interphase is not part of mitosis but is included here as a reminder that interphase (comes BEFORE) or precedes mitosis. (Hence, it has the number 0.)
