At metaphase, sister chromatid pairs are lined up on the equatorial plane of the cell, and attached to spindle fibers (microtubules) at their kinetochores. The signal event of anaphase is the movement of sister chromatids toward opposite poles of the cell, i.e. toward their respective centrioles. This movement is accomplished by depolymerization of spindle fiber microtubules. Finally, at telophase, sister chromatids reach their respective poles, spindle fibers disappear, chromosomes decondense, and nuclear membranes reform around the recently divided DNA as cytokinesis is completed.

In metaphase the chromosomes are lined up on the equator of the spindle, attached to the spindle fibers by their centromeres.
Telophase comes steps later (prophase, metaphase, anaphase, telophase). In telophase, chromosomes have already been split apart at the centromeres and the sister chromatids have been pulled to opposite poles of the spindle. All that splitting happened during anaphase. By the time the cell is in telophase, the chromosomes have arrived at the opposite poles of the spindle and they are turning back into chromatin.

mm following telophase is usually cytokinesis where the cell now splits into two daughter cells (in animal cells - a cleavage furrow kind of pinches the cell in half; in plant cells - a cell wall develops along the center of the parent cell)

Are you dumb?? jk!! ;P
In metaphase they begin to duplicate the DNA, and in telophase they are about to split.
You're welcome! Are you a freshman in high school?
