List the phases of mitosis in order, and give a brief explanation of each phase.

An easy way to remember the stages of mitosis is- preparation may achieve the impossible Prophase-preparationMetaphase-mayAnaphase-achieveTelophase-theInterphase-impossible. Prophaseis the first phase, wherein the genetic material (chromatin) condenses intochromosomes (made up of two chromatids), the centrioles (which produce thespindle fibres) move to opposite poles of the cell, and the nuclear envelopebreaks down. Metaphase is the second phase, where the chromosomes line up at the centre of the cell, and the spindle fibres attach to the centromeres of each. Anaphase happens next, with the chromatids being pulled to opposing ends of the cell. Telophase (and cytokinesis) is where everything returns to normal, the chromasomes decondense back to chromatin, and the nucleoli, and nuclear envelopes reform. Myosin and actin are then responsible for cleaving the cell (Could go over the sliding filament theory if not familiar). Interphase is the phase in between mitosis divisions, It contains two growth phases, a DNA synthesis phase, and checkpoints, which are used to prevent continuous replication in cancer.
