| If cell has 12 chromosomes during interphase, how many exist after mitosis? |
|
Definition
12
Because it's straight copies |

|
Definition
6
Because it splits the chromosomes |

|
Definition
- Prophase
- Metaphase
- Anaphase

|
|
|
Term
|
Definition
- Chromosomes are replicated
- 3 Parts of this phase are G1, S, G2
|
|
|
Term
|
Definition
- Chromatids pair up with sister chromatids to form a tetrad.
- Centrioles appear and begin to move toward opposite ends of the cell
- Crossing over occurs
- Spindle fibers form
|
|
|
Term
|
Definition
- Tetrads line up in the middle of the cell
- Spindle fibers attach to each of the sister chromatids
|
|
|
Term
|
Definition
- Tetrads separate and begin to move to opposite ends of the cell
|
|
|
Term
|
Definition
- 2 Nuclei form
- Nuclear membrane begins to form
- Cytoplasm begins to divide
- All chromosomes are still in the duplicated state
|
|
|
Term
|
Definition
- Cytoplasm divides
- Cells are diploid
- Cell are gentically different
- Protein production is high
|

|
Definition
|
|
Term
Name the phase
Homologous chromosomes line up in the middle in pairs. |
|
Definition
|
|
Term
Name the phase
Cell replicates its chromosomes |
|
Definition
|
|
Term
Name the phase
Homologous chromosomes separate & go to opposite ends of the cell. |
|
Definition
|
|
Term
Name the phase
Spinde forms, DNA coils, chromosomes become tetrads, & crossing over may occur. |
|
Definition
|
|
Term
Name the phase
Events occur in reverse order of prophase. Cell has 1/2 the genetic information, but another cell division occurs so chromosomes are still doubled. |
