What happens during anaphase

During anaphase, the chromosomes are separated into two groups that are genetically identical, and are move to the opposite pole of the cell by the spindle.

Explanation: During cell division, different changes are observed in the cell. In prophase, the chromosomes condense in the nucleus and become visible while the spindle begins to form in the cytoplasm. In metaphase, the chromosomes are arranged in the middle of the cell by the spindle. In anaphase, the spindle separate the chromosomes into two genetically identical groups and move them to opposite ends of the spindle poles. In telophase, there is formation of nuclear membrane around the two identical sets of chromosomes, spreading out of the chromosomes and breaking down of the spindle.

each pair of chromosomes is separated into two identical, independent chromosomes by a structure called the mitotic spindle. The separated chromosomes are then pulled by the spindle to opposite poles of the cell.
