The chromosomes condense and turn into 2-strand chromatids; the nuclear membrane disappears; centrosomes turn to asters and a spindle fiber begins to form.
Metaphase: The chromosomes align at the center of the cell (equatorial plate) and each chromosome is attached to the spindle fiber
Anaphase: The chromatids (1 strand) separate and the centromere divides, where each single strand chromatid ascends to opposite poles of the cell (polar ascension)
Telophase: The cellular membrane cleaves and the nuclear membrane appears again and the asters turn into centromeres once again
We end up with 2 daughter cells each maintaining the same number of chromosomes that the mother cell has (2n) because mitosis is and equational division which preserves the genetic information....
Hope this helps...
The two sets of chromosomes (after S-phase) in the cell are pulled to opposite poles of the cell. The cell is then divided into two, new, separate daughter cells, each with it's own complement of chromosomes.

The cell splits in two and forms two new nuclei.
During the process of mitosis, the nucleus divides!
Nuclear division by mitosis or meiosis
During mitosis, the fibers of each individual chromosome are drawn together forming the tightly packed nucleosomes. The tight packing of nucleosomes may help separate chromosomes during mitosis.
Centrosomes replicate during the S phase of the CELL CYCLE not mitosis. Mitosis is one stage of the cell cycle. Replication does not happen during mitosis(M phase). It happens during the S phase. In fact, the opposite happens chromosomes are consdensed and packaged in preparation for splitting.
In mitosis each daughter cell ends up with the same number of chromosomes as the mother cell.
Prophase.

The equatorial plate happens in mitosis during cytokineses.

This happens during metaphase. I remember this phase because it is the move phaseof mitosis. The m from move matches the m from metaphase.In mitosis, it happens during metaphase.In meiosis, it happens twice and occurs in metaphase 1 and metaphase 2.

Usually mutations or possibly death of the cell.
Another Cell forms that is exactly the same as the previous one.
It happens during Anaphase
Mitosis is broken up into 4 phases, Prophase, Metophase, Anaphase, and Telophase. During these phases the DNA, which was replicated during Interphase, split and 2 new cells are formed.
During mitosis, chromosomes are in their most condensed form during metaphase
