Every living organism falls into one of two groups: eukaryotes or prokaryotes, with cellular structure determining which group an organism belongs to. Prokaryotes are unicellular and lack a nucleus ...

Protein synthesis refers to the process by which cells construct proteins. It's a fundamental cellular mechanism for all living organisms, as proteins carry out enzymatic activities, structural ...

For example, biochemical reactions in a ... In particular, researchers think that some of these "eater" eukaryotes engulfed smaller prokaryotes, and a symbiotic relationship subsequently developed.

plasmids are found in a few simple eukaryotic organisms. Prokaryotic cell DNA is a single molecule, found free in the cytoplasm; additional DNA is found on one or more rings called plasmids.

“This is the most exciting and important paper on big questions about eukaryotic origins and the tree of life in years,” said evolutionary biologist Jeffrey Palmer of Indiana University, Bloomington, ...
