Quizplus · Accepted Answer

The cell in Figure 9.2 is in anaphase of mitosis, during which the sister chromatids are separated and pulled to opposite poles of the cell. Therefore, the next event would be segregation of daughter chromosomes toward the poles. Option A, cell membrane synthesis, occurs during cytokinesis, which is the final stage of the cell cycle, after mitosis. Option B, alignment of chromosomes at the metaphase plate, occurs during metaphase, which is earlier in mitosis. Option D, formation of telophase nuclei, occurs later in mitosis, after the chromosomes have reached the poles. Option E, synthesis of sister chromatids, occurs during S phase of the cell cycle, before mitosis.
