These chromosomes remain attached through their centromeres. ... However, the key function of prophase is the development of scaffolding (spindle apparatus) necessary to move sister chromatids about the (now nucleus-less) cell. ... . . . with each individual chromosome attached to through spindle fibers . . .

So long as the centromeres of a sister chromatid pair remain attached, the visible pair is described as a chromosome. When anaphase of mitosis (or anaphase II of meiosis) begins, the sister chromatids are separated. ... (a) During prometaphase the spindle fibers tug back and forth on sister chromatids...

The centromeres of all of the sister chromatids break simultaneously. ... metaphase - The second stage of mitosis during which the spindle fibers attach to the kinetochore of each sister chromatid structure and pull them to the center of the cell.
