The correct answer is c) anaphase. In anaphase, the sister chromatids, which are joined together at the centromere, separate and move towards opposite ends of the cell.
The phase of mitosis that involves the separation of the sister chromatids is called anaphase. Anaphase is the third phase of mitosis, following prophase and metaphase. During anaphase, the sister chromatids, which are held together by the protein structure called the centromere, separate and move towards opposite ends of the cell. This process ensures that each newly formed cell will receive an equal number of chromosomes.
