Detailed explanation-1: -During anaphase, the sister chromatids separate and begin to migrate to opposite poles of the cell, and a cleavage furrow begins to develop.
Detailed explanation-2: -Anaphase I: In anaphase I, the attachment of the spindle fibers is complete. The homologous chromosomes are pulled apart and move towards opposite ends of the cell.
Detailed explanation-3: -Metaphase leads to anaphase, during which each chromosome’s sister chromatids separate and move to opposite poles of the cell.
Detailed explanation-4: -During anaphase A, the chromosomes move to the poles; during anaphase B, the spindle poles move apart as interpolar microtubules (Fig. 2(D) and (E)) elongate and slide past one another. Many cells undergo both anaphase A and B motions, which can occur simultaneously or sequentially.
Detailed explanation-5: -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.
