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 ...

Prokaryotic and Eukaryotic Cells: The cell is the basic unit of life and forms the building blocks of all living organisms. It was discovered by Robert Hooke In 1665. Some cells have membrane-bound ...

Eukaryotes are organisms whose cells possess a nucleus enclosed within a cell membrane, making up one of the three domains of life, Eukaryota. They include multicellular organisms such as plants, ...

Electron cryotomography (ECT) can reveal the structure of intact cells in a native state in 3D to macromolecular (∼4 nm) resolution. ECT bridges the resolution gap between atomic structures of ...

Bacteria and archaea use protein filament systems to organize cellular processes in time and space. Filaments can act as static scaffolds or as dynamic motors. In some cases, these filament systems ...
