Cell division. Immunofluorescent light micrograph of a cell (centre) during the metaphase stage of mitosis (cell division). It is surrounded by interphase (resting) cells. During metaphase, the DNA- containing chromosomes (yellow/orange) attach to the microtubules (green) and form a line (the metaphase plate) on the microtubule spindle. The microtubules pull the chromosomes apart towards either end of the cell. The cell will eventually split in two, forming genetically- identical daughter cells. Immunofluorescence uses antibodies to attach fluorescent dyes to specific cell tissues.
