What Happens?
What is Anaphase?
The stage of mitosis in which the chromosomes move to opposite ends of the nuclear spindle.

In our words: when two chromatids separate and become a new chromosome, so then it stretches out the cell making the ends push apart.
About Anaphase
In the cell cycle there are three steps to show how a cell grows and divides. The steps are; Inerphase, Mitosis, and Cytokinesis.
Anaphase is the third step in the mitosis phase. It goes Prophase, Metaphase, Anaphase, and Telophase.
Before anaphase begins, the replicated chromosomes, called sister chromatids, are aligned at along the middle of the cell. During anaphase, each pair of chromosomes is separated into two identical, independent chromosomes. The chromosomes are separated by a structure called the mitotic spindle. The mitotic spindle is made of many long proteins called microtubules, which are attached to a chromosome at one end and to the pole of a cell at the other end. The sister chromatids are separated simultaneously at their centromeres. The separated chromosomes are then pulled by the spindle to opposite poles of the cell.
