Archaea do not have an endoplasmic reticulum. The prokaryotic cell has a nucleoid region with no actual membrane- bound nucleus. Ribosomes on the rough endoplasmic reticulum in eukaryotic cells translate mRNA into proteins. This process is preceded by transcription occurring in the nucleus. So, archaea having no nucleus do not require an endoplasmic reticulum to translate DNA, they simply use ribosomes in proximity to the nucleoid region.
What else can I help you with?
Ribosomes are found on which organelle?
Ribosomes are found in all organisms Archaea, eukarya, prokarya
Is the ribosome a plant structure or animal structure?
The ribosome is not specific to plants or animals; it is a universal cellular structure found in all living organisms. Ribosomes are responsible for protein synthesis in cells by translating mRNA into amino acids to build proteins.
Which is not a kingdom in the eukarya domain?
Bacteria archaea
The sites of protein synthesis are?
Protein synthesis occurs at ribosomes, which can be found in the cytoplasm of a cell. In eukaryotic cells, proteins can also be synthesized on ribosomes located on the rough endoplasmic reticulum.
Do archaea possess linear chromosomes?
Yes, archaea do possess linear chromosomes.
Ribosomes are found on which organelle?
Ribosomes are found in all organisms Archaea, eukarya, prokarya
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.
Why do bacteria have 70s ribosomes while eukaryotes have 80s ribosomes?
Bacteria have 70S ribosomes, consisting of a 50S and a 30S subunit, while eukaryotes have 80S ribosomes, made up of a 60S and a 40S subunit. The difference in size and composition is due to evolutionary divergence; bacterial ribosomes are more closely related to the ribosomal RNA of archaea than to eukaryotic ribosomes. This distinction is important for antibiotic targeting, as certain drugs can selectively inhibit bacterial ribosomes without affecting eukaryotic ribosomes.
Is the ribosome a plant structure or animal structure?
The ribosome is not specific to plants or animals; it is a universal cellular structure found in all living organisms. Ribosomes are responsible for protein synthesis in cells by translating mRNA into amino acids to build proteins.
What organisms have ribosomes?
Ribosomes are found in all living organisms, including bacteria, archaea, and eukaryotes like plants, animals, fungi, and protists. Ribosomes are responsible for protein synthesis in cells by translating messenger RNA into proteins.
What cell organelles are common to all six kingdoms?
All six kingdoms of life—Archaea, Bacteria, Protista, Fungi, Plantae, and Animalia—share several common cell organelles, including the cell membrane, ribosomes, and cytoplasm. The cell membrane regulates the entry and exit of substances, ribosomes are essential for protein synthesis, and cytoplasm provides a medium for biochemical reactions. However, certain organelles, like the nucleus or mitochondria, are not found in all kingdoms, particularly the prokaryotic ones (Archaea and Bacteria).
What are facts about the kindgom archaea?
about archaea
Select all that apply. Which characteristics do Archaea and Bacteria have in common?
Archaea and Bacteria share several characteristics, including being prokaryotic organisms, meaning they lack a nucleus and membrane-bound organelles. Both groups have a similar size and shape, typically consisting of single-celled organisms. Additionally, they reproduce asexually, primarily through binary fission. Both Archaea and Bacteria also possess ribosomes for protein synthesis, although their ribosomal RNA differs.
What do the ribosomes in the plant do?
Ribosomes are dense-looking granules formed of two parts. They may be attached to the endoplasmic reticulum or free in the cytoplasm. Ribosomes are the sites where amino acids are assembled into proteins in the process of protein synthesis.
What is the common scientific name for domain archaea?
Firstly, there is no such thing as a 'common scientific name'; that is a contradiction, containing two opposites. The scientific name for the Archaea is Archaea.
Are archaea autotroph's?
Archaea are both heterotrophs And autotrophs!
What is a commmon characteristic for archaea?
Archaea are prokaryotic cells.
