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 ...

Planctomycetes form a distinctive phylum of the Bacteria, having a unique combination of features such as peptidoglycan-lacking proteinaceous cell walls, and intracellular membranes that form separate ...

Bacteria and Archaea are two of the three domains of life. Both must have evolved from the putative Last Universal Common Ancestor (LUCA). One hypothesis is that this happened because the cell ...

Bacteria are single-celled organisms that are pretty much everywhere: in the ground, in the ocean, on your hands and in your gut. While some are harmful, most are not — and some are even beneficial to ...

Cells are the building blocks of all living organisms. Test your knowledge of the structure of cells in preparation for your National 5 Biology exam. Looking for more cell structure revision? There is ...

AMES, Iowa – Two new discoveries from Edward Yu’s Iowa State University laboratory are adding to the scientific understanding of how bacteria resist antibiotics. Yu and his research group have just ...

Researchers have discovered a type of organelle, a fundamental cellular structure, that can turn nitrogen gas into a form that is useful for cell growth. The discovery of the structure, called a ...

For bacteria, the first line of defense is the cell wall, which keeps toxins such as antibiotics out. Now, researchers have discovered a key mechanism that bacteria use to build their cell walls, ...
