Detailed explanation-1: -In fact, Archaea and Eukarya form a monophyletic group, not Archaea and Bacteria. These relationships indicate that archaea are more closely related to eukaryotes than to bacteria, even though superficially archaea appear to be much more similar to bacteria than eukaryotes.

Detailed explanation-2: -Both Bacteria and Archaea encode only a single RNAP that is responsible for transcription of the entire genome, while Eukarya encode several RNAPs with specialized activities that generate gene-family specific transcripts [30. Biochemistry, RNA polymerase. StatPearls. StatPearls Publishing; 2020.

Detailed explanation-3: -Archaea and bacteria have generally similar cell structure, but cell composition and organization set the archaea apart. Like bacteria, archaea lack interior membranes and organelles. Like bacteria, the cell membranes of archaea are usually bounded by a cell wall and they swim using one or more flagella.

Detailed explanation-4: -All of life can be divided into three domains, based on the type of cell of the organism: Bacteria: cells do not contain a nucleus. Archaea: cells do not contain a nucleus; they have a different cell wall from bacteria. Eukarya: cells do contain a nucleus.

Detailed explanation-5: -Similar to bacteria, archaea do not have interior membranes but both have a cell wall and use flagella to swim. Archaea differ in the fact that their cell wall does not contain peptidoglycan and cell membrane uses ether linked lipids as opposed to ester linked lipids in bacteria.
