mitosis (redirected from mitotically)

mitosis /mi·to·sis/ (mi-to´sis) a method of indirect cell division in which the two daughter nuclei normally receive identical complements of the number of chromosomes characteristic of the somatic cells of the species.mitot´ic

Mitosis shown as occurring in a cell of a hypothetical animal with a diploid chromosome number of six (haploid number three); one pair of chromosomes is short, one pair is long and hooked, and one pair is long and knobbed.

mi·to·sis (m-tss) n. pl. mi·to·ses (-sz) 1. The process in cell division by which the nucleus divides, typically in four stages (prophase, metaphase, anaphase, and telophase) resulting in two new nuclei, each of which has exactly the same chromosome and DNA content as the original cell. Also called indirect nuclear division, karyokinesis, mitotic division. 2. The entire process of cell division including division of the nucleus and the cytoplasm. mi·totic (-ttk) adj. mi·toti·cal·ly adv.

mitosis,

n a type of cell division that occurs in somatic cells and results in the formation of two genetically identical daughter cells containing the diploid number of chromosomes characteristic of the species.

mitosis

the ordinary process of cell division which results in the formation of two daughter cells, and by which the body replaces dead cells. The two daughter cells receive identical diploid complements of chromosomes, which are characteristic of somatic cells. Cell division that results in haploid reproductive cells is known as meiosis. The period between mitotic divisions is called interphase. Mitosis itself occurs in four phases: prophase, metaphase, anaphase and telophase.

Originally, the term mitosis referred only to the division of the nucleus, which can occur without cytokinesis in certain fungi and in the fertilized eggs of insects. As used now, it usually refers to mitotic cell division.
