What are the salient features of Three domain classification.

Explanation

1. Carl Woese and his coworkers classified organisms based on the difference in 16s rTRNA genes.
2. This system adds the taxon 'domain' higher than the kingdom.
3. Prokaryotes are separated into two domains - Bacteria and Archaea and all the Eukaryotes are placed in the domain Eukarya.
4. Archaea appears to have more in common with the Eukarya than the Bacteria.
5. Archaea differ from bacteria in cell wall composition and differs from bacteria and eukaryotes in membrane composition and rRNA types.
