Mitosis. Animation showing the prophase and metaphase stages of mitosis (nuclear division). Chromatin (green) begins to condense. Centrioles (beige, top) divide into two pairs and begin migrating to opposite poles of the cell. Fibres extend from the centromeres (grey) and cross the cell to form the mitotic spindle. The nuclear envelope (yellow) then breaks down, and the fully condensed and paired chromosomes migrate to the centre of the cell, attaching to the spindle fibres. The chromosome pairs will be pulled apart, leaving each new cell with one copy of each chromosome. For the next stages of mitosis, anaphase and telophase, see K004/0957. | |
