Term
|
Definition
| The part of the cell cycle where there is a "gap". cell grows and functions, makes more cytoplasm, and more organelles. |
|
|
Term
|
Definition
| cell replicates(synthesizes) an additional copy of all nuclear DNA |
|
|
Term
|
Definition
| cell grows and functions, makes more cytoplasm and more organelles. |
|
|
Term
|
Definition
| cell divides through the process of mitosis, which produces two gentically identical daughter cells. It is the division of the nucleus and the genetic material. |
|
|
Term
|
Definition
| chromosomes are DNA+histone proteins. The DNA is coiled around the histone protein and fits into a tight formation which is a chromosome. |
|
|
Term
|
Definition
| The center of a chromosome |
|
|
Term
|
Definition
| Consists of G1 S and G2 stages. The 4 unreplicated chromosomes become replicated and consist of two sister chromatids. |
|
|
Term
|
Definition
| The point of which the animal cells begin to pinch off. This occurs during the cytokinesis in animals,fungi, and slime molds. occurs when a ring of actin and myosin filaments contracts inside the cell membrane, causing it to pinch inward. |
|
|
Term
|
Definition
| occurs when a ring of actin and myosin filaments contracts inside the cell membrane, causing it to pinch inward in a cleavage furrow. |
|
|
Term
|
Definition
| occurs as vesicles are trasported from the Golgi apparatus to the middle of the dividing cell. These vesicles fuse to form a cell plate. |
|
|
Term
|
Definition
| The point in the middle of the plant cell where all of the vesicles fuse together. |
|
|
Term
|
Definition
A structure that forms during mitosis that produces mechanical forces that:
It is made of-Polar microtubules and Kinetochore microtubules |
|
|
Term
|
Definition
| All eukaryotic cells have a microtubule organizing center (MTOC) at each pole- in animals cells, these are called centrosomes. |
|
|
Term
|
Definition
| remain stationary during anaphase; they shorten because tubulin subunits of the microtubles are lost from their plus ends at the kinetochore. |
|
|
Term
| Dyneins and other Kinetochore motor proteins |
|
Definition
| are attached to the kinetochore's fibrous crown and "walk" toward the minus end of the spindle fiber. |

|
Term
|
Definition
| Chromosomes condense, and spindle apparatus begins to form. |
|
|
Term
|
Definition
| Nuclear envelope breaks down Kinetochore microtubles contract chromosomes at kinetochore. |
|
|
Term
|
Definition
| Chromosomes complete migration to the middle of the cell |
|
|
Term
|
Definition
| Sister chromatids separate. Chromosomes are pulled to opposite poles of the cell. |
|
|
Term
|
Definition
| The nuclear envelope re-forms and the spindle apparatus disintegrates. |
