Question

Which statement is true about domain archaea?

• A. They differ from both prokaryotes and eukaryotes
• B. They completely differ from prokaryotes
• C. They resemble eukarya in all aspects
• D. They have some novel features absent in other prokaryotes and eukaryotes

Answer 1

Answer: (D)

They have some novel features absent in other prokaryotes and eukaryotes

Domains Archaea contains single-celled microorganisms. These are prokaryotes. They do not have a true nucleus or membrane-bound organelles. They lack peptidoglycan in the cell wall. However, they have some novel features absent in other prokaryotes and eukaryotes. Instead of ester bonds like in prokaryotes and eukaryotes, they have ether bonds connecting fatty acids to molecules of glycerol.

Thus, the correct answer is 'They have some novel features absent in other prokaryotes and eukaryotes.'
