Vast numbers of different prokaryotic microorganisms shape the biosphere, with diverse metabolic capabilities. Determination of genome sequences for a wide range of bacteria and archaea now requires ...

Results reported in a recent Science paper provide the first experimental evidence to support the hypothesis that prokaryotes possess a defence system that might be analogous to eukaryotic RNA ...

All complex life on Earth, including plants and animals, are made up of eukaryotic cells, which are more sophisticated than ...

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

Eukaryotic and prokaryotic cells produce minute (40-1000 nm) membrane vesicles that are released into the local environment. These extracellular vesicles (EVs), including exosomes and microvesicles, ...

Mars does not have a magnetosphere. Any discussion of humans ever settling the red planet can stop right there, but of course ...

Archaea and bacteria, on the other hand, are prokaryotic, meaning they don’t contain such structures. While these two other ...

CaMKII activates the HRI/eIF2α signaling pathway and inhibits the proteotoxicity induced by proteasome inhibition through ...
