Definition
| the majority of the cell's life is spent in this phase; it is made up of the G1, S, and G2 phases; during this time, the cell carries on metabolism, grows, and then prepares for a period of cell division |
|

Term
|
Definition
| the longest phase of mitosis; the chromatin coils into chromosomes, the nuclear envelope begins to disappear, the centrioles migrate to opposite ends of the cell, and the spindle fibers begin to appear |
|
|
Term
|
Definition
| this is the phase of mitosis when the doubled chromosomes become attached to the spindle by their centromeres and are lined up down the middle of the cell. |
|
|
Term
|
Definition
| the phase of mitosis during which the centromeres split, sister chromatids separate and begin to move to opposite ends of the cell towards the centriole |
|
|
Term
|
Definition
| this is the final phase of mitosis; the chromosomes begin to unwind into chromatin; the spindle breaks down; a nucleolus reappears; and a new nuclear envelope begins to form around each set of chromosomes. There is also an evident cleavage furrow between the two new nuclei |

Definition
| a football shaped, cage-like structure consisting of thin fibers made of microtubules |
|
|
Term
