Each chromosome visible as 2 chromatids joined at centre. Nuclear envelope breaks into small pieces Centrioles organise fibrous proteins into the spindle 1 of 4 Metaphase Chromosomes held on spindle at middle of the cell Each chromosome attached to spindle on either side of its centromere (the circle separating the chromatids) 2 of 4 Anaphase Chromatids break apart from the centromere and line up at opposite ends of the cell by the spindle 3 of 4 Telophase Nuclear envelopes reform around the chromatids that have reached the poles of the cell Each new nucleus has same number of chromosomes as original parent cell Nuclei genetically identical to each other 4 of 4
