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*

Back
Telophase
•
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
