NEET BIOLOGY

Detailed explanation-1: –Domain archaea have single-celled microorganisms. They are prokaryotes.

Detailed explanation-2: -The two prokaryote domains, Bacteria and Archaea, split from each other early in the evolution of life. Bacteria are very diverse, ranging from disease-causing pathogens to beneficial photosynthesizers and symbionts. Archaea are also diverse, but none are pathogenic and many live in extreme environments.

Detailed explanation-3: -Archaea and bacterial cells lack organelles or other internal membrane-bound structures. Therefore, unlike eukaryotes, archaea and bacteria do not have a nucleus separating their genetic material from the rest of the cell.

Detailed explanation-4: -Thus, the correct answer is ‘They have some novel features absent in other prokaryotes and eukaryotes.

Detailed explanation-5: -Archaea and Bacteria Both are composed of prokaryotic cells, which are cells without a nucleus. In addition, both domains are composed of species that reproduce asexually (asexual reproduction) by dividing in two.
