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.
Anaphase is a very important stage of cell division. It ensures that duplicated chromosomes, or sister chromatids, separate into two equal sets. This separation of chromosomes is called disjunction. Each set of chromosomes will become part of a new cell. If chromosomes fail to separate properly during anaphase, nondisjunction has occurred.
