Title: What is the difference between cytokinesis and mitosis?
Post by: thedoc on 01/04/2012 09:55:01

ipex90 asked the Naked Scientists:
   Some cells in our bodies do not go through cytokinesis, only mitosis. How do these cells differ from other cells?

What do you think?

What cells are supposed to do this?   Mitosis is the division of the nucleus, home to DNA, while cytokinesis is the division of the actual cell and dividing up its contents.   So if this happened you'd have a cell with  two nuclei, and therefore twice the DNA it's supposed to have.   I wouldn't think this could happen.

Well you have the syncytia in skeletomuscular cells, but they arise from fusion of uninuclear cells to become polynuclear, not mitosis without cytokinesis..

Maybe the topic starter is talking about a pathological process of cytokinesis inhibition?
