Scientists identified two key distinctions related to the DNA replication system and the membrane. The replication system of archaea is largely unrelated to that of bacteria, but it is homologous ...

All of the usual stuff we think of as “life”—things like trees, fungi, and animals—are eukaryotes, meaning that their cells contain a nucleus and other membrane-bound organelles.

"Archaea is one of three lineages of life, alongside Bacteria and Eukarya (organisms whose cells have a membrane-bound ...

This idea is supported, they say, by the fact that most genes in modern eukaryotes are actually bacterial, and not archaeal, in origin, and that eukaryotic membranes are made up of phospholipids that ...

Since the late 1980s, all life forms have been split into three groups on the phylogenetic tree of life: bacteria, archaea, and eukaryotes. Eukaryotes and archaea have long been considered “sister ...

Bacteria and archaea cells just don’t have what it ... The cell’s universal energy currency, ATP, is manufactured at the cell membrane. But as cells grow larger, their surface area to volume ...
