While prokaryotic cells do not have membrane-bound structures, they do have distinct cellular regions (Figure 1). In prokaryotic cells, DNA bundles together in a region called the nucleoid. Primitive ...

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 ...

Prokaryotic cells have evolved numerous machineries to swim through liquid or crawl over surfaces. Perhaps the most common of these are the well-studied bacterial flagella and the unrelated archaeal ...
