|
Term
|
Definition
- Chromosomes condense and become visible
- Spindle fibers emerge from the centrosomes
- Nuclear envelope breaks down
- Nucleolus disappears
|
|
|
Term
|
Definition
- Mitotic spindle is fully developed, centrosomes are at opposite poles of the cell
- Chromosomes are lined up at the metaphase plate
- Each sister chromatid is attached to a spindle fiber originating from opposite poles
|
|
|
Term
|
Definition
- Cohesin proteins binding the sister chromatids together break down
- Sister chromatids (now called chromosomes) are pulled toward opposite poles
- Non-kinetochore spindle fibers lengthen, elongating the cell
|
|
|
Term
|
Definition
- Chromosomes arrive at opposite poles and begin to decondenese
- Nuclear envelope material surrounds each set of chromosomes
- The mitotic spindle breaks down
