anaphase

n. stage in cell division in which the cells begin to separate (Biology)

Anaphase, from the ancient Greek ανα (up) and φασις (stage), is the stage of mitosis when chromosomes separate in a eukaryotic cell. Each chromatid moves to opposite poles of the cell, the opposite ends of the mitotic spindle, near the microtubule organizing centers.Anaphase is preceded by metaphase, by the end of which fully condensed sister chromatids are arranged in a straight line down the midline of the cell, defining a structure referred to as the metaphase plate. Spindle fibres, which are microtubules containing γ-tubulin and other Microtubule-associated proteins extend from the poles to the centromeres. The point of contact is a protein complex called the kinetochore, and these fibres are sometimes referred to as kinetochore fibers or k-fibers. Other spindle fibres do not come in contact with the chromosomes but either connect directly with spindle fibres from the opposing pole as overlap microtubules or interpolar microtubules or with the cell cortex as astral microtubules.
