| Nondividing Stage | ||
| DNA replication (S phase), | ||
|
Preparation for mitosis (G2 phase) |
||
|
Prophase |
The DNA is duplicated (this keeps the number of chromosomes in the daughter cells equal to the parent cells) The DNA is tightly coiled into chromosomes (these are visible) Nuclear envelope disappears |
"proceed" |
|
Metaphase |
The lining up of the chromosomes along the midline. The centrioles line up at opposite poles and the spindles begin to attach to the centromeres of the chromosomes
|
In the "middle" |
|
Anaphase |
This stage is characterized by the separation of sister chromosomes and their movement to the opposite poles of the spindles. |
"And away we go" |
|
Telophase |
The chromosomes reach the opposite poles and the nuclear
envelope begins to reform around each of the groups of chromosomes.
The sides of the cell form a furrow and the cytoplasm divides Animals divide from the outside in and plants divide from the inside out. |
"The end" |

Daughter cells |
The 2, 2n daughter cells enter Interphase |
