![]() This even alignment is due to the counterbalance of the pulling powers generated by the opposing kinetochore microtubules, analogous to a tug-of-war between two people of equal strength, ending with the destruction of B cyclin. ![]() ![]() In metaphase, the centromeres of the chromosomes convene themselves on the metaphase plate (or equatorial plate), an imaginary line that is equidistant from the two centrosome poles. Preceded by events in prometaphase and followed by anaphase, microtubules formed in prophase have already found and attached themselves to kinetochores in metaphase. Metaphase accounts for approximately 4% of the cell cycle's duration. These chromosomes, carrying genetic information, align in the equator of the cell before being separated into each of the two daughter cells. ![]() Metaphase (from Ancient Greek μετα- ( meta-) 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). ![]() Stages of early mitosis in a vertebrate cell with micrographs of chromatids ![]()
