Bacteria from domain arachea differ from bacteria from domain monera based on what

Question

1. Cell walls contain peptidoglycan
2. Plasma membrane contains glycerol linked to fatty acids
3. A different sequence of bases in the rRNA
4. Their occurrence in artic environments

Answer 1

The correct answer would be:

3. A different sequence of bases in the rRNA

Bacteria from the domain Archaea differ from bacteria from the domain Monera in terms of their rRNA sequence. Archaea possess rRNA sequences that are distinct from those found in Monera. However, this difference does not apply to all bacteria in the domain Monera, as some bacteria within this domain do not possess peptidoglycan in their cell walls (option 1) and have plasma membranes containing glycerol linked to fatty acids (option 2). Additionally, the occurrence of bacteria from the domain Archaea in Arctic environments (option 4) is not exclusive to them, as bacteria from the domain Monera can also be found in such environments.
