Detailed explanation-1: -Anaphase. After metaphase is complete, the cell enters anaphase. During anaphase, the microtubules attached to the kinetochores contract, which pulls the sister chromatids apart and toward opposite poles of the cell (Figure 3c). At this point, each chromatid is considered a separate chromosome.
Detailed explanation-2: -Anaphase: spindle fibers separate sister chromatids to opposite poles of the cell.
Detailed explanation-3: -So, the correct option is ‘Anaphase’.
Detailed explanation-4: -During anaphase, the sister chromatids are separated simultaneously at their centromeres. The separated chromosomes are then pulled by the spindle to opposite poles of the cell. Anaphase ensures that each daughter cell receives an identical set of chromosomes.
