Answer 1

Answer:

The spindle fibers bring the chromosomes together and then pull them apart.

Explanation:

Metaphase and anaphase are phases in the process of cell division. The metaphase precedes the anaphase.

During the mitotic metaphase, the chromosomes are organized and located together in the center of the cell. The chromosomes must be organized at this phase to ensure their correct distribution in the daughter cells (product of mitosis).

During anaphase, chromosomes are dragged into the asters of the cell and thus, pulled appart. Homologous chromosomes are intended for opposite poles. this is the paternal chromosome goes to one of the asters and the maternal to the opposite aster.
