What could happen if there was a mistake durning prophase, metaphase, anaphase and telophase?

Mutations might be possible if there was a mistake made

During prophase the DNA condenses into chromosomes and fibers begin to extend from the centromeres, the part of the chromosomes that links the two arms, or chromatids. During metaphase, the chromosomes move to the center of the cell and are aligned in a area known the metaphase plate. Anaphase is the phase of mitosis during which the chromosomes begin to move toward opposite sides of the cell. The chromosomes move towards the centriols in a way that one chromosomes from each pair move towards each pole. During telophase, the chromosomes reach the poles and new nuclear membranes form around the chromosomes, creating the nuclei for two new cells. The chromosomes decondense and the cell splits into two daughter cells, each with a nucleus.
