|
|
Chromosomes attach to mitotic spindles and align along the equator of the cell.
|
|
|
The cell grows and carries out normal cell processes and DNA replicates.
|
|
|
Chromosomes reach poles of the cell, nuclear envelope, reforms, nucleolus reappears, and chromosomes decondense.
|
|
|
Microtubules shorten moving chromosomes to opposite poles.
|
|
|
Nuclear membrane disintegrates, the nucleolus disappears, chromosomes condense, mitotic spindle begins to form between the poles.
|
Detailed explanation-1: -Telophase begins when the decondensing daughter chromatids arrive at the poles, the kinetochore microtubules disappear, and the nuclear envelope reforms around the decondensing chromosomes to form the two daughter nuclei (Benavente, 1991).
Detailed explanation-2: -During telophase, a nuclear membrane forms around each set of chromosomes to separate the nuclear DNA from the cytoplasm. The chromosomes begin to uncoil, which makes them diffuse and less compact.
Detailed explanation-3: -During telophase, the chromosomes begin to decondense, the spindle breaks down, and the nuclear membranes and nucleoli re-form. The cytoplasm of the mother cell divides to form two daughter cells, each containing the same number and kind of chromosomes as the mother cell.
Detailed explanation-4: -During telophase, the nuclear envelopes reform around the new nuclei in each half of the dividing cell. The nucleolus, or ribosome producing portions of the nucleus return. As the cell has finished moving the chromosomes, the main parts of the spindle apparatus fall depolymerize, or fall apart.
Detailed explanation-5: -The nucleolus and the nuclear membrane reappear and the nucleus revert to the interphasic condition with the chromatin appearing as delicate threads. The nuclear membrane reforms from fragments of the parent cell’s nuclear envelope as well as other portions of the inracellular membranes.
