Question

Which of the following is NOT a characteristic of members of the Domain Archaea?

a. They carry out unusual metabolic processes.

b. They contain distinctive ribosomal RNA.

c. They contain nuclei.

d. They live in extreme environments.

Answer 1

Members of the Domain Archaea do not have nuclei as they are prokaryotic cells, distinguishing them from eukaryotic cells. They are known for living in extreme environments and having unique ribosomal RNA and cell wall composition.

Step-by-step explanation:

The characteristic that is NOT a feature of members of the Domain Archaea is c. They contain nuclei. Members of the Archaea domain are known for their unique characteristics, which set them apart from other domains such as Bacteria and Eukarya. One essential trait of Archaea is that they are prokaryotic organisms, meaning they do not have a nucleus or any other membrane-bound organelles.

These organisms often live in extreme environments and have distinctive ribosomal RNA. Unlike Bacteria, Archaea have cell walls that do not contain peptidoglycan, but both lack nuclei. The presence of a nucleus is synonymous with eukaryotic cells, not prokaryotic cells belonging to the Archaea or Bacteria domains.
