|
|
final stage of the cell cycle. |
cytokines |
|
|
This stage contains four phases. |
Mitosis |
|
|
In this stage the DNA makes an exact copy of its self. |
Interphase |
|
|
In this stage the cell prepares for division by producing structures it needs. |
Interphase |
|
|
This stage takes the most time. |
Interphase |
|
|
In plant cells a cell plate forms. |
Cytokinesis |
|
|
This stage is the first stage of the cell cycle. |
Interphase |
|
|
In this stage the cytoplasm divides and organelles are divide. The parent cell becomes two daughter cells. |
Cytokinesis |
|
|
In this stage the nucleus turns into two nuclei. |
Mitosis |
|
|
In this stage the cell grows to its full size. |
Interphase |
|
|
A DNA strand looks like a. |
Twisted ladder |
|
|
A rung of a DNA strand is made up of. |
A pair of nitrogen base |
|
|
-In this phase the centromere splits and the chromatids move to opposite ends of the cell. |
Anaphase |
|
|
-In this phase the chromosomes stretch out and the nuclear envelope forms around the nuclear region. |
Telophase |
|
|
-In this phase the chromosomes line up in the center of the cell and attach to spindle fibers. |
Metaphase |
|
|
-In this phase the nuclear envelope breaks down. |
Prophase |
|
|
-In this phase the chromatin condenses to form rod like structures called chromosomes. |
