What makes up the three domain system?

Answered

The three-domain system comprises three primary domains: Archaea, Bacteria, and Eukarya. Archaea and Bacteria are prokaryotic organisms that differ in their rRNA sequences, membrane lipids, and cell wall compositions. Eukarya includes all eukaryotic organisms, characterized by cells with membrane-bound nuclei and organelles. This classification system is based on molecular and genetic evidence, particularly the analysis of ribosomal RNA sequences.
