Cells spend the most time in this phase.
|
Interphase (90%)
|
|
Describe interphase
|
the chromosomes are being replicated so that during cell division, a complete copy of the genome can be distributed to both daughter cells
|
|
Describe Prophase
|
During prophase, the chromosomes condense, and the centriole pairs (in animals) separate and move towards the opposite poles of the cell.
The spindle apparatus forms between them, and the nuclear membrane dissolves, allowing the spindle fibers to interact with the chromosomes. |
|
Describe Metaphase
|
The centriole pairs are now at opposite poles of the cell.
The fibers of the spindle apparatus attach to each chromatid at the centromere to align the chromosomes at the center of the cell (equator), forming the metaphase plate. |
|
Describe Anaphase
|
The centromeres split so that each chromatid has its own distinct centromere, thus allowing sister chromatids to separate.
The sister chromatids are pulled toward the opposite poles of the cell by the shortening of the spindle fibers. Spindle fibers are composed of microtubules. |
|
Describe Telophase
|
The spindle apparatus disappears.
A nuclear membrane forms around each set of newly formed chromosomes as the original or parent nucleus. The chromosomes uncoil, resuming their interphase form. |
|
Describe Cytokinesis
|
the phase where the cell finally divides
