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 ...

Flagella are primarily used for cell movement and are found in prokaryotes as well as some eukaryotes. The prokaryotic flagellum spins, creating forward movement by a corkscrew shaped filament. A ...

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 ...
