They discovered that some archaea use unusual types of enzymes called [FeFe]-hydrogenases. The archaea making these ...

There are two major types of hypothesis about how eukaryotes and their nuclei may have originated (Poole & Penny 2007). One of these involves fusion between cells from domains Archaea and Bacteria ...

After eight years of study, they found 31,000 unique types of archaea and more than 377,000 unique types of bacteria in their samples. These types are called ASVs (amplicon sequence variants ...

While previous research had described bidirectional promoters in eukaryotes, as well as in a few bacteria and archaea species, the new study establishes divergent transcription—the reading of genes in ...

Indeed, archaea and bacteria appear very similar biologically (members of both groups consist of tiny cells without much internal structure) and different from eukaryotes. However, until ...
