Question

Archaea are most similar to
Protists
Bacteria

Answer 1

Archaea are most similar to **Bacteria** in terms of their prokaryotic cell structure and the fact that both groups lack a nucleus and membrane-bound organelles. However, they are distinct from Bacteria at the molecular level, particularly in their genetic and biochemical properties. Archaea are more closely related to Eukarya (which includes Protists, plants, animals, and fungi) than they are to Bacteria in terms of certain genetic sequences and cellular processes.
