The main difference between prokaryotic and eukaryotic cells lies in their structure. Prokaryotic cells and eukaryotic cells are the two types of cells that exist on Earth. There are several ...

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 ...

A new method exposes key details of the mechanism behind calcium signaling in prokaryotes for the first time. Working in a Listeria monocytogenes model, researchers from Umeå University (Sweden) led ...

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 ...

Scientists generally agree that eukaryotes, the domain of life whose cells contain nuclei and that includes almost all multicellular organisms, originated from a process involving the symbiotic union ...
