Key Concepts

Phylogenetic Classification

Bacteria and archaea belong to separate domains, reflecting deep evolutionary divergences. Their genetic sequences, particularly in ribosomal RNA, reveal distinct lineages and evolutionary histories, establishing them as fundamentally different groups despite both being prokaryotes.

Membrane Lipid Composition

The cell membranes of bacteria and archaea differ in their chemical makeup. Bacterial membranes typically contain fatty acids linked by ester bonds, while archaeal membranes feature isoprenoid chains attached by ether bonds, which contributes to the unique stability and adaptability of archaea, especially under extreme conditions.

Cell Wall Composition

Bacteria usually have cell walls that contain peptidoglycan, a polymer that provides structure and protection. In contrast, archaea lack peptidoglycan; instead, they often possess cell walls composed of different compounds like pseudopeptidoglycan or protein-based layers, marking a significant biochemical distinction between the two domains.
