Only Eukaryotes have a true nucleus. The word means "new" "nut". The nut means nucleus. This cell have membranes around their organelles including the nucleus. Prokaryote means "before" "nut". These do not have membrane around the nucleus. Bacteria are prokaryotes.

What domain do humans fit in?
Taxonomy is the branch of biology that's job is to name and classify species. On the broadest spectrum of classification of all living things, you have three overarching groups called Domains: Bacteria Domain, Archaea Domain, and Eukaraya Domain. Bacteria and Archaea Domains consist of prokaryotes, that is organisms with prokaryotic cells. Eukaraya Domain consists of eukaryotes, that is organisms with eukaryotic cells. Humans have eukaryotic cells and are therefore in the Eukarya Domain.
What domain most likely has organisms that are Unicellular have no nucleus and contain DNA?
Both eubacteria and archaea are domains of prokaryotic organisms. That means they are unicellular and have no organelles or nucleus. They do have DNA because all living organisms have DNA. Prokaryotes have no nucleus, are unicellular, and contain DNA.
What is the kingdom of unicellular prokaryotic organism?
The unicellular prokaryotes are one-celled organisms. They are located on two domains: the Archaea and the Eubacteria. The third domain, Eukarya, contain multi-cellular organisms.
Which 2 kingdoms contain all the prokaryotic organisms?
"There are two kingdoms of prokaryotes. These are the bacteria (or eubacteria) and the archaebacteria (or the Archaea)."
Do all cells except bacteria contain organelles?
Eukaryotic cells contain membrane bound compartments, prokaryotic cells don't. Membrane bound compartments form organelles. Prokaryotes are a group of organisms made up of both bacteria and archaea, which you may not have studied- they used to be known as archaeabacteria as people thought they were a kind of bacteria, but current scientific opinion is that they're separate. So... no, it's not only bacteria that don't have organelles, archaea don't either.
What are the 3 biological domains?
Archaea, Bacteria, and Eukarya. Archaea are some of the oldest single celled organisms on the planet due to their capability to survive in extreme conditions. Bacteria, also called eubacteria or true bacteria, are composed of prokaryotic cells, but their cell walls have different structures, components in them. Eukarya are composed of eukaryotic cells and contain most the multicellular organisms in our world such as animals, plants, protists, and fungi. Hope this helps.
Archaae eukarya and what are the three main domains?
The three main domains of life are Bacteria, Archaea, and Eukarya. Archaea and Bacteria are prokaryotic, while Eukarya includes all organisms with eukaryotic cells, such as plants, animals, fungi, and protists.
Which domains contain organisms that are made of prokaryotic cells?
The domain that consists of prokaryotic cells are bacteria and archaea.

Is eubacterium a type of Eukaryotic?
Yes
What is an explanation of the three domain system of classification in taxonomy?
The three-domain system classifies all known life forms into three domains: Bacteria, Archaea, and Eukarya. Bacteria and Archaea are prokaryotic, while Eukarya includes all eukaryotic organisms. This classification is based on genetic and cellular characteristics, reflecting evolutionary relationships among organisms.
What domain most likely has organisms that are Unicellular have no nucleus and contain DNA?
Both eubacteria and archaea are domains of prokaryotic organisms. That means they are unicellular and have no organelles or nucleus. They do have DNA because all living organisms have DNA. Prokaryotes have no nucleus, are unicellular, and contain DNA.
Examples of archaeabacteria?
Many scientists hypothesize that the Archaea are the closest modern relatives of Earth's first living cells. Called "universal ancestors," these are the cells from which all other life is believed to have evolved. This hypothesis is based on two types of evidence. Genetic analyses indicate that the Archaea domain branches off of the phylogenetic tree at a point that is closest to the tree's root. Furthermore, it has been observed that many of the Archaea prefer to live in extremes of temperature, salt concentration, and pH-environmental conditions thought to be similar to those found on Earth over 3.5 billion years ago, when life first originated.The Archaea share certain characteristics with Bacteria, others with Eukarya, and have some characteristics that are unique. For example, cells of the Archaea are structurally more similar to Bacteria, live predominantly as single cells, and have cell walls, although the walls do not contain the complex material called peptidoglycan that is a signature molecule of the Bacteria. While some Eukarya have cell walls, it is not a universal characteristic of that domain, and the Eukarya walls are composed of chitin or cellulose, neither of which occurs in cell walls of Archaea or Bacteria. Like the Bacteria, the Archaea lack a membrane-enclosed nucleus and their DNA exists in a circular form. On the other hand, their DNA is associated with histones, a characteristic of Eukarya, and their cell machinery (such as proteinsynthesizing enzymes and RNA polymerases) more closely resembles that found in the Eukarya. The lipids that comprise their membranes are unique, resembling neither the Bacteria nor the Eukarya.Certain members of the Archaea are able to produce methane gas, another unique characteristic. Methane is one of the most important greenhouse gases. An Italian scientist named Alessandro Volta first discovered it as a type of "combustible air" over two hundred years ago. He trapped gas from marsh sediments and showed that it was flammable long before we knew that it was produced by members of the Archaea that lived in salt marsh sediment. Other important habitats for Archaea with this unique ability include the digestive tracts of animals and sewage sludge digesters.For the source and more detailed information concerning this subject, click on the related links section (Answers.com) indicated below.
Differentiate between bacteria and archaea?
The bacteria cell wall is made of peptidoglycan, while archaea cell walls lack peptidoglycan. Also, the archaea cell membrane contain ether linkages, while the bacteria cell membrane contains ether bonds.
What is the kingdom of unicellular prokaryotic organism?
The unicellular prokaryotes are one-celled organisms. They are located on two domains: the Archaea and the Eubacteria. The third domain, Eukarya, contain multi-cellular organisms.
Which 2 kingdoms contain all the prokaryotic organisms?
"There are two kingdoms of prokaryotes. These are the bacteria (or eubacteria) and the archaebacteria (or the Archaea)."
What are 3 domains animals are classified into?
Animals are classified into three domains: Archaea, Bacteria, and Eukarya. However, animals specifically belong to the domain Eukarya, which includes organisms that have a membrane-bound nucleus and other membrane-bound organelles within their cells. The other two domains contain organisms that are not animals.
