mitosis
nuclear division to produce two genetically identical daughter cells
prophase
chromatin network condenses to form rod-like chromosomes…each chromosome is divided into 2 identical threads called chromatids held by a centromere…nuclear membrane starts disintegrating…spindle fibres start forming as centrioles move to opposite poles
metaphase
spindle fibre is fully formed…chromosomes arrange themselves at the equator of the spindle…chromosomes attach to spindle by their centromere
anaphase
chromatids move to opposite poles of the cell, first the centromere pulled my microtubules…two groups of chromosomes attach at each pole towards the end
telophase
two identical groups of chromosomes have arrived at the poles…spindle fibres disintegrate…nuclear membranes form around chromosomes to form the nuclei…chromosomes uncoil to chromatin network…cytokinesis starts
