Why are archaea more closely related to eukaryotes than bacteria?
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.
How do bacteria and archaea differ?
Archaea: cell membrane contains ether linkages; cell wall lacks peptidoglycan; genes and enzymes behave more like Eukaryotes; have three RNA polymerases like eukaryotes; and extremophilesBacteria: cell membrane contains ester bonds; cell wall made of peptidoglycan; have only one RNA polymerase; react to antibiotics in a different way than archea do.
Archaea and eubacteria were found to be most different because?
Archaea and eubacteria are most different in terms of their cell membrane structure, as archaea have unique membrane lipids, and their genetic machinery, which is more similar to eukaryotes than bacteria. These differences reflect distinct evolutionary lineages and adaptations to different environments.
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.
What is the description of archbacteria?
Archaea are single-celled microorganisms with characteristics similar to both bacteria and eukaryotes. They are prokaryotic organisms that lack a nucleus and membrane-bound organelles, but have unique cell structures and biochemistry. Archaea can be found in a wide range of environments, from extreme conditions like hot springs and deep-sea vents to more moderate habitats like soil and oceans.
Why are archaea more closely related to eukaryotes than bacteria?
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.
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.

How are organisms in the domain Eukarya different from those in the domain Archaea?
Archaea have no nucleus

Compared to Eukaryotes Bacteria and Archaea have surface-to-volume ratios causing nutrient exchange and growth rates.?
Bacteria and Archaea typically have higher surface-to-volume ratios compared to eukaryotes due to their smaller size and simpler structures. This increased ratio facilitates more efficient nutrient exchange across their cell membranes, allowing for faster growth rates. In contrast, eukaryotes, being larger and more complex, often have lower surface-to-volume ratios, which can limit their nutrient uptake and cellular processes. As a result, prokaryotes like bacteria and archaea can often reproduce and metabolize more rapidly than eukaryotic cells.
Is cryptosporidium a virus fungus or bacteria?
It's neither.. its considered apart of the protist kingdom. Fungi have their own kingdom as does bacteria, animals, archaea and plants. Plants, Animals, Fungi and Protists are all called Eukaryotes because they all are similar in that they all have a nucleus and things called "membrane bound organelles". They are generally considered more complex then Archaea and Bacteria. The amazing thing about Eukaryotes is that originally they were once bacteria as well. However millions of years ago a bacteria engulfed another bacteria which kept living inside the other bacteria and released nutrients from inside the bacteria which actually helped it survive. That original bacteria turned into the "membrane bound organelles" we find in eukaryotes today!!!!!! The nucleus of the eukaryotes (which bacteria and archaea dont have) may have arisen from an engulfed virus but we still dont know if that is correct. :S Some Protists can cause infection while most don't.
How do the two groups of prokaryotes differ?
They differ because one is cool and the other one is awesome
How bacteria and archaea differ in their ribosomal entities?
Bacteria and archaea differ in their ribosomal RNA (rRNA) sequences and the structure of their ribosomes. Bacterial ribosomes are composed of 70S units, consisting of 50S and 30S subunits, while archaeal ribosomes also have a 70S structure but differ in their protein composition and rRNA sequences. Additionally, the ribosomal proteins in archaea are more similar to those found in eukaryotes than in bacteria. These differences reflect their distinct evolutionary lineages and contribute to variations in protein synthesis mechanisms.
What is an example of Archaea?
Amoebas are not a bacteria and are protozoa which are eukaryotes and NOT Archaea . Which unlike other bacteria does not have peptidoglycan and is more related to eukaryotes than bacteria that is why the name changed for Archaeabacteria to just Archaea, lives in extreme conditions but can be found in other places,such as 30%of marine microbes, and does not cause infections to humans . One example of Archaea is Methanococcus jammaschii which is one of the first to make this classification clear. Protozoa are eukaryotes ,while Archaea are prokaryotes without membrane bound organelles. Halobacterium Korarchaeota are only found in in high temperature hydrothermal environments
