A new technique that constructs models of primitive cells has demonstrated that the structure of a cell's membrane and cytoplasm may be as important to cell division as a cell's enzymes, DNA, or RNA.

All life on earth depends upon the process of mitosis or cell division in which the chromosomal content of a cell is equally divided between two new cells. For mitosis to occur, the chromosomes in ...

The process of mitosis has made more clear, thanks to recent research. A new study describes how Topo 2, an enzyme that disentangles DNA molecules and is essential for proper cell division. At this ...

FtsZ is required for the formation of a ring structure, known as the Z ring, at the site of cell or organelle division. Contraction of the Z ring leads to fission of the cell or organelle. The FtsZ ...
