Prophase• The cell begins to break down
structures and build others up• Chromosomes are formed in
an X shape connected by the Centromere
• The mitotic spindle begins to “capture” chromosomes
• The nuclear envelope breaks down
Back
Metaphase• The spindle has now captured all the Chromosomes and aligned them in the center at the metaphase plate
• The cell will then check to make sure all Chromosomes are attached correctly to their spindle checkpoints.
Back
Anaphase• Cohesin* is broken down, allowing the
sister chromatids to separate
• Microtubules elongate and push apart, which allows the cell the grow taller
• This is driven by motor proteins*
BackFind the definition to * words here
• The cell is mostly finished in it’s diving process
• The mitotic spindle is broken down
• The new nuclei form for the daughter cells
• The chromosomes return to their original “stringy state”

Cohesin- The protein “glue” that holds the sister chromatids together
Motor Proteins- molecular machines that “walk” along microtubule tracks and carry cargo
