The steps of mitosis are:
Interphase: Here the cell has a nucleus, centrioles, and the chromosomes are not yet visible.
Prophase: the nucleus starts to deteriorate, the chromosomes are now visible, and the spindel fiber arrears. The spindel fiber helps the cell strech.
Metaphase: during metaphase the chromosomes start to line up.
Anaphase: during anaphase the chromosomes separate and the spindel fiber helps each half of the chromosome move to one side and the other half to the other side.
Telophase: During telophase the new cells form their nucleus and have half of the chromosomes.
Then: 2 new cells are formaed!!
