• ​DNA begins to thicken and condense (smaller/compact)

• Centriole pairs/centrosomes begin to migrate to opposite poles, spindle fibers forming between them

• ​Nuclear membrane and nucleolus dissolve

​

​

​Prophase

​

​centrioles

• Centrioles moved to opposite poles​ with stretched out spindle fibers

• Sister chromatids aligned along equatorial plate.

• Spindle apparatus/mitotic spindle fully formed.

  ​

​Remember: the chromosomes are replicated. They are two identical sister chromatids attached to each other

​

​Metaphase

​

​spindle fibers

• ​Spindle fibers shorten and pull apart sister chromatids at the centromore and drag the chromatids to opposite poles

• ​Split sister chromatids become chromosomes

​Anaphase

​

• A nuclear membrane forms around each group of chromosome

• Spindle fibers break apart​

• DNA uncoils/disperses​

• Cleavage furrow forms to separate the cytoplasm​ (plant cell - cell plate)

  ​signals cytokinesis

• division of the cytoplasm

• the membrane pinches closed, forming

  a separate cell around each nucleus.​

​

​Cytokinesis

​

• Recreation 2 new daughter cells

• New cells enter

  interphase and begin

  the cycle again.
