Metaphase (from Ancient Greek μετα- beyond, above, transcending and from Ancient Greek φάσις (phásis) 'appearance') is a stage of mitosis in the eukaryotic cell cycle in which chromosomes are at their second-most condensed and coiled stage (they are at their most condensed in anaphase). [1]
Also meganucleus. The larger of the two types of nuclei which occur in pairs in the cells of some ciliated protozoa. Macronuclei are highly polyploid and responsible for directing vegetative reproduction, in contrast to the diploid micronuclei, which have important functions during conjugation. macrophage Any of a class of relatively long-lived phagocytic cells of the mammalian immune system ...

This abrupt shift is caused by the activation of the anaphase-promoting complex and its function of tagging degradation of proteins important toward the metaphase-anaphase transition. One of these proteins that is broken down is securin which through its breakdown releases the enzyme separase that cleaves the cohesin rings holding together the ...

This interval includes the G 2 phase and metaphase (annotated as "Meta."). Further information: Karyotype G 2 phase , Gap 2 phase , or Growth 2 phase , is the third subphase of interphase in the cell cycle directly preceding mitosis .

The spindle checkpoint, also known as the metaphase-to-anaphase transition, the spindle assembly checkpoint (SAC), the metaphase checkpoint, or the mitotic checkpoint, is a cell cycle checkpoint during metaphase of mitosis or meiosis that prevents the separation of the duplicated chromosomes until each chromosome is properly attached to the ...
