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 ...

In most prokaryotes, and indeed eukaryotes, after chromosome replication and segregation of the daughter chromosomes to the two halves of the cell, cell division takes place and two progeny cells are ...
