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 ...

Why have bacteria never evolved complex multicellularity? A new hypothesis suggests that it could come down to how prokaryotic genomes respond to a small population size. Every organism visible to the ...

This method for directly enriching the 5´ end of primary transcripts enables the determination of transcription start sites at single-base resolution. Coupled with long read sequencing, the method ...

Contrary to popular belief, bacteria have organelles too. Scientists are now studying them for insights into how complex cells evolved. Open a basic biology textbook published decades ago or one ...
