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 ...

Two recent reports have identified a new Sec synthase that catalyzes the last step in the generation of this aminoacyl-tRNA in eukarya and archaea.

In fact, Asgard archaea appeared almost heaven-sent for research: they turned out to be a missing link between archaea and eukaryotes – that is, between archaea and organisms whose cells contain a ...

“This should have a major effect on textbook treatment of these subjects.” Since the late 1980s, all life forms have been split into three groups on the phylogenetic tree of life: bacteria, archaea, ...

As a postdoctoral researcher in Brett Baker’s lab at the University of Texas at Austin, Leão explored the archaeal origins of eukaryotes, or eukaryogenesis. Leão and his team used a database of ...

Starting from LUCA, i.e., the hypothesized last universal common ancestor from which the three domains of life -- the Bacteria, the Archaea, and the Eukarya -- originated, the researchers found ...

In eukaryotes, microtubules are responsible for transport processes within the cell, and in Asgard archaea, they may have played a key role in the evolution of these microorganisms. In their study ...

nov. (strain WWM1085). Archaea are a distinct domain of life—along with bacteria and eukaryotes (i.e., organisms with a cell nucleus such as animals, plants and fungi). Although they appear ...
