of the following features which are common to bacteria and archaea?
481723
Archaea and bacteria are both prokaryotes, meaning they do not have a nucleus and lack membrane-bound organelles. They are tiny, single-cell organisms which cannot be seen by the naked human eye called microbes.

The basic difference in Eubacteria and Archaebacteria is based upon its cell wall structure and features related to DNA replication , transcription and translation machinery. Archaebacteria have ether linked membrane lipids with branched chains as compared to eubacteria.

- The bacteria in the kingdom Archaebacteria are prokaryotic. - They live in extreme conditions such as: high acidity, boiling water, freezing water, and high salt concentration. - They are very primitive organisms, believed to be the first organisms on the planet. - They are both producers and consumers.

There are three domains of life: Bacteria (also known as Eubacteria), Archaea, and Eukarya. ... The Bacteria and Archaea have been grouped together and called Prokaryotes because of their lack of a nucleus, but the Archaea are more closely related to the Eukaryotes than to the Bacteria.

Key points: Prokaryotes are single-celled organisms belonging to the domains Bacteria and Archaea. Prokaryotic cells are much smaller than eukaryotic cells, have no nucleus, and lack organelles. All prokaryotic cells are encased by a cell wall.

Bacteria. Bacteria (singular: bacterium) are a major group of living organisms. Most are microscopic and unicellular, with a relatively simple cell structure lacking a cell nucleus, and organelles such as mitochondria and chloroplasts. Bacteria are the most abundant of all organisms.
628277
Key Points There are three notable common traits of bacteria, 1) lack of membrane-bound organelles, 2) unicellular and 3) small (usually microscopic) size. Not all prokaryotes are bacteria, some are archaea, which although they share common physicals features to bacteria, are ancestrally different from bacteria.

The common characteristics of Archaebacteria known to date are these: (1) the presence of characteristic tRNAs and ribosomal RNAs; (2) the absence of peptidoglycan cell walls, with in many cases, replacement by a largely proteinaceous coat; (3) the occurrence of ether linked lipids built from phytanyl chains and (4) in ...

The common features of prokaryotic and eukaryotic cells are: DNA, the genetic material contained in one or more chromosomes and located in a nonmembrane bound nucleoid region in prokaryotes and a membrane-bound nucleus in eukaryotes.

Archaea and bacteria are the representatives of the prokaryotes and belong to the kingdom Monera. ... They were earlier classified as bacteria only and obtained name as “archaebacteria”, but due to the presence of certain unique features, they are now termed as 'archaea'. They are inhabitants of very extreme environments.

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. ... In contrast, some eukaryotes do have cell walls, while others do not.
