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 ...

Pili are short, hair-like structures on the cell surface of prokaryotic cells. They can have a role in movement, but are more often involved in adherence to surfaces, which facilitates infection, and ...

COLD SPRING HARBOR, N.Y. (Nov. 24, 2010) --The bacterial cell is often thought of as a "bag of enzymes"—a single compartment with limited internal structure, a primitive cell cycle, and relatively ...

To test if the quality and concentration of dissolved nitrogen (N) species could be a selective force in shaping bacterioplankton community structure, competition for various N compounds among five ...

New research has revealed that the structure of a bacteriophage, a virus infecting bacteria, resembles that of certain dangerous viruses that infect people. Studying this bacteriophage reveals various ...

A new study shows that eukaryotic ribosomes can be modified to respond to antibiotics in the same way that prokaryotic ribosomes do. According to researchers at the University of Illinois Chicago, the ...
