The statement "The chromosomes are moving towards the poles of the cell" describes a specific phase in the process of cell division, particularly during mitosis or meiosis.

In the context of mitosis, this movement occurs during anaphase. During anaphase, the sister chromatids, which were previously aligned at the metaphase plate, are pulled apart by the spindle fibers and move towards opposite poles of the cell. This ensures that each daughter cell will receive an identical set of chromosomes.

In the context of meiosis, this movement can occur during anaphase I or anaphase II. In anaphase I, homologous chromosomes are separated and move towards opposite poles. In anaphase II, the sister chromatids are separated and move towards opposite poles, similar to what happens in mitosis.

To summarize:

  • The movement of chromosomes towards the poles of the cell occurs during anaphase.
  • In mitosis, this is specifically during anaphase.
  • In meiosis, this can occur during anaphase I (homologous chromosomes) or anaphase II (sister chromatids).
