Noun1.cytokinesis - organic process consisting of the division of the cytoplasm of a cell following karyokinesis bringing about the separation into two daughter cells
meiosis, miosis, reduction division - (genetics) cell division that produces reproductive cells in sexually reproducing organisms; the nucleus divides into four nuclei each containing half the chromosome number (leading to gametes in animals and spores in plants)
mitosis - cell division in which the nucleus divides into nuclei containing the same number of chromosomes
biological process, organic process - a process occurring in living organisms

Primitive cells had to divide with very little biology, and electrostatics could have played a central role in mitosis and cytokinesis. In the cytoplasmic medium (cytosol) that exists within biological cells, electrostatic fields are subject to strong attenuation by ionic screening, and therefore decrease rapidly over a distance of several Debye lengths.
The asexual reproduction of plants is made possible by a combination of two processes termed mitosis and cytokinesis. Mitosis is the normal division of a cell nucleus that occurs as a plant grows, enlarging from embryo to maturity (Figure 5-2).
It has been reported that the ms1ms1 plants were characterized by formation of coenocytic microspores, resulting from the failure of cytokinesis after Telophase II (Albertsen and Palmer, 1979; Chen and Palmer, 1985; Chen et al., 1987).
Although several embryos have been fixed during cytokinesis, polar lobe formation has not been observed.
The autosomal recessive form is mainly due to DOCK8 (Dedicator of cytokinesis 8) and Tyk2 (Tyrosine kinase 2) mutations and pre-dominant clinical manifestations are severe eczema, recurrent skin and lung infections1,2.
Tyrosine kinase 2 (TYK2) and dedicator of cytokinesis 8 (DOCK8) genes mutations are implicated in recessive forms [7, 8].
At sampling periods immediately after cytokinesis, chromosomes were observed at the start of second meiosis.
It is suggested that endomitosis without anaphase B, as well as the blockage of cytokinesis, results in megakaryocyte polyploidization.
Surprisingly, lack of Drpl gene does not affect cytokinesis. Given the central role played by Drp1 in mitochondrial fission and that this process is critical to assure an equal distribution of these organelles between the two daughter cells in each cell division, the results obtained by Ishihara and colleagues were puzzling.
During cytokinesis, aurora B kinase (ABK) relocalizes from centromeres to the spindle midzone, where it is thought to provide a spatial cue for cytokinesis.
Interestingly, approximately 16% of identified proteins had functions related to cellular processes such as cell movement, cytokinesis, cell cycle, chromosomal segregation, and cell communication.
