The correct sequence of steps in mitosis is:
-
Prophase - The chromatin condenses into visible chromosomes, and the nuclear envelope begins to break down. The mitotic spindle starts to form.
-
Metaphase - The chromosomes align at the cell's equatorial plate (metaphase plate), and spindle fibers attach to the centromeres of the chromosomes.
-
Anaphase - The sister chromatids are pulled apart and move toward opposite poles of the cell.
-
Telophase - The chromatids reach the poles of the cell, the nuclear envelopes reform around each set of chromosomes, and the chromosomes begin to de-condense.
-
Cytokinesis - Although technically not a part of mitosis, this step occurs concurrently with telophase, where the cytoplasm divides to form two separate cells.
So the order is: Prophase, Metaphase, Anaphase, Telophase (and then Cytokinesis).
