Question

In the five-kingdom classification system, all prokaryotes belong to the kingdom Monera. Which of the following best explains a reason why prokaryotes were separated into different domains, Eubacteria and Archaea?
Answer
Archaea contain a single DNA loop, while Eubacteria contain double-stranded, helical DNA.
Archaea contain RNA, while Eubacteria contain both DNA and RNA.
Unlike Eubacteria, Archaea are capable of surviving in extreme environments.
Unlike Eubacteria, Archaea do not have a membrane-bound nucleus.
