Archaea are more closely related to eukaryotes than bacteria because they share similar genetic and molecular characteristics, such as the presence of introns in their genes and similar RNA polymerases. This suggests a closer evolutionary relationship between archaea and eukaryotes compared to bacteria.

What is the difference between bacteria and archaea in terms of their genetic makeup and evolutionary history?
Bacteria and archaea are both types of single-celled microorganisms, but they differ in their genetic makeup and evolutionary history. Archaea have unique genetic characteristics that set them apart from bacteria, such as different cell membrane structures and genetic sequences. In terms of evolutionary history, archaea are believed to be more closely related to eukaryotes (organisms with complex cells) than to bacteria. This suggests that archaea and bacteria evolved separately and have distinct evolutionary paths.
Which group of prokaryotes do scientists think may be ancestors of eukaryotes?
Scientists think that archaea may be the group of prokaryotes that are most closely related to the ancestors of eukaryotes. This is based on genetic and biochemical similarities between archaea and eukaryotes, as well as the shared presence of certain cellular structures and processes.
Which prokaryotic group is most closely related to eukaryotes?
i believe the answer is Cyanobacteria, because they are photosynthetic, contain chlorophyll as eukaryotic plantae do. Also most algae is eukaryotic with the exception of Cyanobacteria which is a prokaryote. Also it is theorized that plant cells used endosymbiosis to engulf cyanobacteria as a means of producing energy via photosynthesis. ( Cyanobacteria have their own DNA)
Why was the kingdoms monera divided into two separate kingdoms?
None of them have a true nucleus. One-celled (unicellular) organisms whose DNA is not contained inside a nucleus are called prokaryotes (PRO care ee oats). They are bacteria. Bacteria mostly absorb their food. Some have chlorophyll. These bacteria can be round, rod-shaped, or spiral shaped. The other phylum is the cyanobacteria. They are often called blue-green bacteria. They can make their own food using chlorophyll and are mostly blue-green in color. source: http://edhelper.com/ReadingComprehension_54_23.html
Is bacteria the same as a microbe?
They are merely definitions, with one of them encompassing the other. A microorganism or microbe is an organism that is microscopic (usually too small to be seen by the naked human eye). Microorganisms include bacteria, fungi, archaea, and protists; microscopic plants (called green algae); and animals such as plankton, the planarian and the amoeba.Therefore, it would be similar to asking is a Pine tree the same thing as a tree?
How are Archaea more closely related to eukaryotes than to bacteria?
Arche bacteria are much closer to eukaryotes.Bacteria also have some similarities. NO. Archaea, Bacteria and Eukaryota. Bacteria are more closely related to the more complex organisms (Eukaryotes). Archaea are now considered in their own domain. The Archaea in plankton are the most abundant organism on the planet.
What evidence exists to support the idea that archaea are more closely related to eukaryotes rather than to bacteria?
The presence of certain genetic and molecular features, such as introns, histones, and similarities in the RNA polymerase structure, suggest a closer evolutionary relationship between archaea and eukaryotes. Additionally, comparative genomics studies have shown that archaea share more genes and metabolic pathways with eukaryotes than with bacteria. This evidence supports the hypothesis that archaea and eukaryotes share a common ancestry.

All the organisms classified into the domain?
The domain system classifies organisms into three main domains: Bacteria, Archaea, and Eukarya. Bacteria are single-celled prokaryotic organisms, Archaea are also single-celled prokaryotes but are more closely related to eukaryotes than bacteria, and Eukarya includes all eukaryotic organisms, which are typically multicellular and have a nucleus.
How are anchaebacteria different from eubacteria?
Archaea differ from bacteria in their genetic makeup, cell membrane composition, and metabolic pathways. Archaea have a different cell wall structure, lack peptidoglycan, and have unique DNA replication and transcription systems. They are often found in extreme environments and are more closely related to eukaryotes than to bacteria.
The most recent phylogenetic data suggests that bacteria and archaea may be more closely related than archaea and eukarya true or false?
TRUE
Which group of prokaryotes do scientists think may be ancestors of eukaryotes?
Scientists think that archaea may be the group of prokaryotes that are most closely related to the ancestors of eukaryotes. This is based on genetic and biochemical similarities between archaea and eukaryotes, as well as the shared presence of certain cellular structures and processes.
Which are more closely related to complex organisms bacteria or archaea explain?
On basis of cladistic analysis higher organisms are more closly related to Archaea .
What group is closely related to Archeabacteria?
Archaea are closely related to Bacteria, and together with Eukarya, they are the three domains of life. While Archaea and Bacteria share some similarities, such as lacking a nuclear membrane and having circular DNA, they also have distinct genetic and biochemical differences that separate them as two distinct domains.
How are archae and bacteria different as domains?
Archaea and Bacteria are both domains of life, but they differ in genetic and structural characteristics. Archaea are more closely related to Eukarya than Bacteria, based on genetic studies. Additionally, Archaea often thrive in extreme environments, while Bacteria are more diverse in their habitats.
Are protists more closely related to animals or to bacteria?
Protists are different from any other organisms found in the animal or bacteria kingdom. For this reason, they are seen as heterotrophic or autotrophic by biologists and botanists.
What is the largest group of Archaea?
Like bacteria, Archaea are single-celled organisms lacking nuclei. Most are cocci, bacilli, or spiral forms (although unusual shapes do exist). Unlike bacteria, Archaea lack peptidoglycan in their cell wall. At this point Archaea are not known to cause disease in humans or animals.Members of the kingdom Archaea had been considered to be bacteria until examination of their unique rRNA sequences showed that they are a distinct type of prokaryote. And despite being prokaryotes, Archaea appear to be more closely related to Eukaryotes than to Bacteria.This is the largest group of Archaea. Methanogens derive their name from the fact that methane is one of their metabolic byproducts.The largest group of Archaea is methanogens.
