A)Sister chromatids separate from each other.

D)The condensed chromosomes relax.
E)Spindle microtubules anchor to kinetochores.

Question

Quizplus · Accepted Answer

During anaphase of mitosis, sister chromatids separate from each other and are pulled towards opposite poles of the cell by the spindle fibers. This process ensures that each daughter cell receives a complete set of chromosomes. Homologous chromosomes separate during anaphase I of meiosis, but not during anaphase of mitosis. The spindle-assembly checkpoint occurs during metaphase and ensures proper alignment of chromosomes before they are separated during anaphase. The condensed chromosomes do not relax during anaphase, but rather continue to be pulled towards the opposite poles of the cell. Spindle microtubules anchor to kinetochores during prometaphase and metaphase, but not during anaphase when they are responsible for pulling the sister chromatids apart.
