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
