Parts of Model• Nuclear Membrane: 2 small string tied in a circle• Cell Membrane: Large string tied in a circle• Spindle Fibers: Colored string (4 dark blue)• Chromatin/Chromatid: Yarn (2 multicolored)• Chromosomes: 4 colors of pipe cleaners (4 pairs)• Centrioles: 2 straw pieces

Interphase• Cell is in normal function• Nucleus is visible• Nuclear membrane is intact• DNA replicates (chromosomes are
copied, # is doubled) • G1 phase• Synthesis (chromatin is
replicated)

Prophase• Mitosis begins• Cell begins to divide• Nuclear membrane dissolves• Centrioles (poles) appear and
move to opposite sides of the cell• Spindle fibers form between the
centrioles (poles)

Metaphase • chromosomes attach to spindle fibers• Spindles line chromosomes up in the
center of the cell

Anaphase • Chromosomes separate and
begin to move to opposite ends of the cell

Telophase • Chromosomes uncoil into
chromatin• Nuclear membrane re-forms (2
new nuclei formed)• Mitosis ends

Cytokinesis• Cells completely divide into two
individual daughter cells• Each daughter cell has the exact
same chromosomes as the parent cell• 2 new cells return to interphase
