(Biology) the third stage of mitosis, during which the chromatids separate and migrate towards opposite ends of the spindle. See also prophase, metaphase, telophase2. (Biology) the corresponding stage of the first division of meiosis[C19: from ana- + phase]an•a•phase (ˈæn əˌfeɪz)
n. the stage in mitosis or meiosis following metaphase in which the chromosomes move away from each other to opposite ends of the cell. [1885–90] an`a•pha′sic, adj. an·a·phase (ăn′ə-fāz′) The stage of cell division in which the doubled set of chromosomes separates into two identical groups that move to opposite ends of the cell. In mitosis, anaphase is preceded by metaphase and followed by telophase.

anaphase [an´ah-fāz] the third stage of division of the nucleus of a cell in either meiosis or mitosis.an·a·phase (an'ă-fāz), The stage of mitosis or meiosis in which the chromosomes move from the equatorial plate toward the poles of the cell. In mitosis a full set of daughter chromosomes (46 in humans) moves toward each pole. In the first division of meiosis one member of each homologous pair (23 in humans), consisting of two chromatids united at the centromere, moves toward each pole. In the second division of meiosis the centromere divides and the two chromatids separate with one moving to each pole. [G. ana, up, + phasis, appearance] anaphase (ăn′ə-fāz′)n.

[G. ana, up, + phasis, appearance]anaphase A stage in cell division (MITOSIS) in which the separated individual chromosomes migrate to opposite ends of the cell in preparation for the division of the cell into two new individuals.anaphase a stage of nuclear division in eukaryotic cells (see EUCORYOTE), occurring once in MITOSIS and twice in MEIOSIS. The main process involved is the separation of chromosomal material to give two groups of chromosomes which will eventually become new cell nuclei. This important step is controlled by SPINDLE MICROTUBULES (or fibres) which run from the organizing centre at each pole to every chromosome, the point of attachment being the kinetochore of the CENTROMERE (see METAPHASE).Various theories for chromosomal movement have been put forward, including: - active repulsion of chromosomes,
- the idea that when sliding past each other the microtubules may act as tiny muscles (the ‘sliding filament’ theory), and
- a suggestion that the microtubules are disassembled at the poles, so ‘reeling in’ the attached chromosomes.
