Definition
* A period of cellular growth.
* 90% of the cell cycle.
* Includes G1, S, and G2 phases. |
|
|
Term
|
Definition
* chromatin condenses into chromosomes. * nuclear envelope breaks down
* spindles form at opposite "poles" of the cell. |
|
|
Term
|
Definition
* spindle fully develops
* chromosomes align at the metaphase plate |
|
|
Term
|
Definition
* paired chromosomes (sister chromatids) separate and begin moving to opposite ends of the cell.
* Spindle fibers not connected to chromatids lengthen and elongate the cell.
* At the end of anaphase, each pole contains a complete compilation of chromosomes. |
|
|
Term
|
Definition
* Chromosomes are cordoned off into distinct new nuclei in the emerging daughter cells.
* Cytokinesis begins at the beginning of the phase and is completed by the end. |

Term
|
Definition
| A star shaped region that forms around centrosomes on opposite ends of the dividing cell during division. |
|
|
Term
|
Definition
| Microtubules growing from the poles of the cell that move the chromosomes during cell division. |
|
|
Term
|
Definition
| The protein structure on chromatids where the spindle fibers attach during cell division to pull sister chromatids apart. |
