Answer;
All of the above.
- gene sequences of rRNA
- cell membrane properties
- enzymes and metabolic pathways
Explanation;
Among the main differences in genetic make-up between archaea and eubacteria;
- Gene sequences of rRNA ; The rRNA or Ribosomal RNA of Archaea differs as much from that of Bacteria's DNA as it does from the Eukarya's DNA.
- Cell membrane properties ; the lipid membranes of archaea have ether bonds which have branching aliphatic acids, while that of eubacteria have ester bonds with fatty acids.
- Enzymes and metabolic pathway; in terms of metabolic pathways, archaea do not have glycolysis and Kreb's cycles but instead they use other pathways that are similar. Eubacteria on the other hand, follow glycolysis and Kreb's cycle to break down sugars and generate energy for their cells.
