-
This can happen either occasionally during cell wounding or regularly during cytokinesis and meiosis.
-
It is undisputable that mitosis and cytokinesis, although tightly coupled in most cells, can often be uncoupled, suggesting that these two processes are actually independent, even though they usually cooperate to bring about cell division.
-
In the bacterium, equipartition might thus be achieved either if the cell divides at a length for which the homogeneous state is stable or if period-doubling occurs before or at an initial stage of cytokinesis.

-
In plants, actin filaments have been implicated in cytokinesis, cell expansion and development.
-
However these different precytokinesis cell-cycle arrest phenotypes are all imprecise, as the arrested cells repeatedly re-enter S-phase, and show characteristic multinuclear, multikinetoplast and multiflagellar phenotypes.

-
Analysis of the double-mutant phenotype indicated that at the nonpermissive temperature, cells failed to undergo cytokinesis efficiently.
-
In a similar fashion, the final stage of animal cytokinesis is based on de novo formation of the plasma membrane via the interdigitating microtubules known as the midbody.
-
Additionally, cytokinesis blocked cells are thought to be prone to polyploidization if the gap between the daughter nuclei is very small, resulting in incomplete or absent karyokinesis.
-
The key developmental processes of cytokinesis and cell expansion require vesicle trafficking to deposit new wall material and increase plasma membrane area.
-
The ultimate conclusion of one cell cycle is cytokinesis resulting in two identical daughter cells.
-
The frequency of multicentrosomal cells in the mutant's MEF cells was higher, and it commonly occurred concurrently with a binuclear phenotype, suggesting cytokinesis failure etiology.

-
In this type of endosperm, which is the most common in cereals, development starts with several rounds of divisions of the triploid nucleus without cytokinesis.
-
These MN appear to be the consequence of a very high rate of chromosome lagging occurring in multipolar mitoses (preceding the multinucleate state) which are produced when cytokinesis-blocked binucleate cells further divide.
-
Micronuclei are observed in binucleated cells in which cytokinesis has been inhibited.
-
Cells in anaphase, telophase or cytokinesis can be discriminated easily from those in other cell-cycle phases by their typical locations of chromosomes or by their cellular morphology.

The separation of the buds may reflect an additional bud neck defect or the completion of cytokinesis in these mutants.
-
Structural proteins are also used during mitosis and cytokinesis, the processes by which a cell reproduces itself.
-
In the absence of growth inhibition cells are smaller and follow the normal axial budding pattern of haploid cells, in which new cells bud adjacent to the previous site of cytokinesis.

But different proportions of mononucleated and binucleated myocytes may be present, and this possibility complicates the distinction between karyokinesis and cytokinesis.
-
Cytokinesis - The final stage in the process of cell division is known as cytokinesis, which usually begins during late anaphase or early telophase (before mitosis ends) as the nuclear envelope and nucleoli are reforming and the chromosomes are de-condensing (see Figure 1 (f)).
