What goes on in each stage of mitosis?

There are 6 stages of mitosis:
- Interphase-DNA has replicated, but has not formed the condensed structure of chromosome.
- Prophase-DNA molecules progressivly shorten by coiling, to form chromosomes.
- Metaphase-the spindle fibres attach themselves to the centromeres of the chromosomes and align the chromosomes at the equatorial plate.
- Anaphase-the spindle fibres shorten and the centromere splits, separated sister chromatids are pulled along behind the centromeres.
- Telophase-the chromosomes reach the poles of their respective spindles. Nuclear envelope reform before the chromosomes uncoil. The spindle fibres disintegrate.
- Cytokinasis-the process of splitting the daughter cells apart. A furrow forms and the cell is pinched in two. Each daughter cell contains the same number and same quality of chromosomes.
