the _ can help us to understand these phases of cell life |

Term
|
Definition
- cell grows to its full size
- prepares to mitosis by copying its centrioles and DNA
- DNA is in the form of long thin chromatin
|
|
|
Term
|
Definition
- Replicated chromatin thicness and shortens into chromosomes[becomes visable] each chromosomes is made up of 2 sister chromatids that are conected by centromere
- Nuclear membrane breaks down
- Centromere travels to opposite ends of the cell
- Spindle fibers form between the centromere
|
|
|
Term
|
Definition
- chromosomes line up across the center of the cell
- Each chromosomes attaches to a spindle fiber at its centromere
|
|
|
Term
|
Definition
- Centromere of each chrosomsome splits
- Sister chromatids separate to oppostie ends of the cell, along the spindle fiber
- Cell streched out as opposite ends pull
|
|
|
Term
|
Definition
- Nuclear membrane reforms around each group of chromosomes
- Chromsomes [DNA] unwinds to chromatin once again
- Centrioles and spindle fibers disappear
|
|
|
Term
In__ the cell cycle, the cytoplasm divides in the process of _ |
|
Definition
[1] Stage 3 [2] Cytokinesis |
|
|
Term
|
Definition
- Cell membrane pinches in around the middle of the cell, untill 2 daughter cells are formed [plant cells do cell plate formation due to the cell wall]
- each daughter cells DNA is identical to the parent cell
