|
Interphase |
The cell grows to its full size. Produces structures it needs. Ex. - cell makes new ribosomes andproduces enzymes. Makes an exact copy of DNA in its nucleus. DNA is found in the chromatin in thenucleus. DNA contains all the information the cellneeds. |
|
|
Mitosis |
Nucleus divides into two nuclei. One copy of DNA is distributed to each of the twodaughter cells. Divided into 4 phases: Prophase Metaphase Anaphase Telophase |
|
|
Metaphase |
In this phase the chromosomes line up in the center of the cell and attach to spindle fibers. |
|
|
Telophase |
In this phase the chromosomes stretch out and the nuclear envelope forms around the nuclear region. |
|
|
Prophase |
In this phase the nuclear envelope breaks down.In this phase the chromatin condenses to form rod like structures called chromosomes. |
|
|
Anaphase |
In this phase the centromere splits and the chromatids move to opposite ends of the cell. |
|
|
DNA replication |
is the process by which a cell makes an exact copy of its DNA. |
|
|
What are chromatids |
identical strands of chromosomes |
|
|
What forms around the chromatids during mitosis |
two new nuclei |
