|
Term
|
Definition
| spindle fibers form and the centrioles move to opposite sides of the cell. The nuclear membrane disappears. |
|
|
Term
|
Definition
| chromosomes align midway along spindle fibers |
|
|
Term
|
Definition
| chromosomes begin to separate from their daughters. Cytokinesis begins. |
|
|
Term
|
Definition
| identical sets of chromosomes are at opposite ends of the cell. Spindle fibers disappear, nuclear membranes reappear and cytokinesis completes. |

|
|
Term
|
Definition
| one of a pair of newly duplicated chromosomes; pair of matching "sister" chromatids make up the duplicated chromosome |
|
|
Term
|
Definition
| disc extending across the nuclear area on which the chromosomes are found at metaphase just prior to the separation of the chromosomes during mitosis |
|
|
Term
|
Definition
| separates two sets of chromosomes into different cells |
