metaphase (ËmÉtÉËfeÉªz) n 1. (Biology) the second stage of mitosis during which the condensed chromosomes attach to the centre of the spindle. metâ¢aâ¢phase (ËmÉt ÉËfeÉªz) n. the stage in mitosis or meiosis in which the duplicated chromosomes line up along the equatorial plate of the spindle.
After metaphase is complete, the cell enters anaphase. During anaphase, the microtubules attached to the kinetochores contract, which pulls the sister chromatids apart and toward opposite poles of the cell (Figure 3c). At this point, each chromatid is considered a separate chromosome.
