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 ...

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 ...

A quick revision guide covering key concepts, biomolecules, cell organelles, and essential NEET-style MCQs to boost exam ...

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 ...

A new study challenges a popular scenario put forward to explain the arrival of the first eukaryotic organisms. In the beginning, there was boredom. Following the emergence of cellular life on earth, ...
