Deep in hydrothermal vents beneath the Arctic Ocean, scientists have discovered an organism that sheds fresh light on the evolutionary link between simple and complex cellular life. The microbe and ...

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 ...

Many prokaryote species are known to have fluid genomes, with different strains varying markedly in accessory gene content through the combined action of gene loss, gene gain via lateral transfer, as ...

Planctomycetes challenge our concept of the bacterial cell and of a prokaryote as a cell structure type, as well as our ideas about origins of the eukaryote nucleus. Planctomycetes Are Important for ...

A nucleus is one of many membrane-bound compartments that distinguishes our eukaryotic cells from the prokaryotic cells of microorganisms like bacteria. Eukaryotic cells also possess energy-producing ...

There are some major evolutionary jumps that seem to have occurred only once. Eukaryotic cells contain membrane-enclosed structures to perform different functions, and they comprise all forms of ...

Norman Pace has a problem with prokaryotes. It’s not that Pace has anything against the organisms themselves. The microbiologist and RNA scientist from the University of Colorado at Boulder has made a ...
