ARCHAE
FUN FACT: The Archae are thought to be living fossils and survivors of an ancient group of organisms that lived through the gap in evolution between eubacteria and eukaryotes.
- Definition: genetically distinct from domains Bacteria and domain Eukaryote, and often inhabiting extreme environmental conditions.
- Traits that make it unique
- evolved separately from eubacteria and eukaryotes
- similar to eubacteria in being prokaryotes and lacking a cell nuclei.
- they distinguish from them by having a different ribosomal (RNA) structure, having introns in some species and their membrane structure or composition
- similar to eukaryotes by having genes and a couple metabolic pathways that are more more connected to those of eukaryotes. (Ex: their enzymes involved in transcription and translation are very similar)
- different biochemical properties are characteristic of this domain
