Mitosis definition, the usual method of cell division, characterized typically by the resolving of the chromatin of the nucleus into a threadlike form, which condenses into chromosomes, each of which separates longitudinally into two parts, one part of each chromosome being retained in each of two new cells resulting from the original cell.

Definition. noun, plural mitoses. ... Originally, the term mitosis refers only to nuclear division unaccompanied by cytokinesis (which is the division of the cytoplasm), as in the case of some cells like certain fungi and in fertilized egg of many insects. As used now, ...


Mitosis definition is - a process that takes place in the nucleus of a dividing cell, involves typically a series of steps consisting of prophase, metaphase, anaphase, and telophase, and results in the formation of two new nuclei each having the same number of chromosomes as the parent nucleus.


The mitosis process in the cells of eukaryotic organisms follow a similar pattern, but with variations in three main details. "Closed" and "open" mitosis can be distinguished on the basis of nuclear envelope remaining intact or breaking down. An intermediate form with partial degradation of the nuclear envelope is called a "semiopen" mitosis.

Mitosis: Mitosis, a process of cell duplication, or reproduction, during which one cell gives rise to two genetically identical daughter cells. Strictly applied, the term is used to describe the duplication and distribution of chromosomes, the structures that carry the genetic information.


mitosis [mi-to´sis] the ordinary process of cell division resulting in the formation of two daughter cells, by which the body replaces dead cells. The daughter cells have identical diploid complements of chromosomes (46 in human somatic cells). Cell division that results in haploid reproductive cells is known as meiosis. The period between mitotic ...


"Meiosis II looks like mitosis," Hoyt told Live Science. "It's an equational division." In other words, by the end of the process, the chromosome number is unchanged between the cells that enter ...
