What else can I help you with?
What is the composition of the rough er?
It has ribosomes [that create proteins] that give it a rough looking surface.
Why can antibiotics that selectively target bacterial ribosomes cause side effects for patients?
It has to do with the difference in composition of ribosomes in the eukaryotic cells versus the prokaryotic cell.
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.
What criteria are used to classify organisms?
the criteria for classifying bacteria1- morphology , shape2-size3-mode of locomotion4-composition of cell wall5-reproduction6-composition of cell7-production of ribosomes
Do eubacteria contain ribosomes?
Yes, eubacteria do contain ribosomes.As in eukaryotic cells, the ribosomes are the sites of polypeptide synthesis.Like the ribosomes in other organisms, eubacterial ribosomes are constructed of RNA and proteins. However, the details of their chemical composition are different from those of the other major groups (eukaryotes and archaeobacteria) and are characteristic of eubacteria.The chemistry of the ribosomes in mitochondria and chloroplasts is like that of eubacteria.
Is ribosomes in prokaryotic cells and eukaryotic cells?
Yes, ribosomes are found in both prokaryotic and eukaryotic cells. They are responsible for protein synthesis in all cells by translating mRNA into a specific sequence of amino acids to form proteins. While the basic structure and function of ribosomes are similar in both types of cells, there are some differences in the size and composition of ribosomes between prokaryotic and eukaryotic cells.
Is a ribosome a prokaryote or a eukaryote?
Better to say prokaryotes have ribosomes. Eukaryotes also have ribosomes, the " workbench " on which polypeptides are synthesized, but the ribosomes are somewhat different in size and composition between prokaryotes and eukaryotes, though they do the same job.
What is the other name of ribosomes?
Ribosomes are commonly referred to as "protein factories" due to their essential role in synthesizing proteins by translating messenger RNA (mRNA). Additionally, they are sometimes called "ribosomal particles" or "ribosomal RNA (rRNA) complexes," highlighting their composition of ribosomal RNA and proteins.
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.
What tiny organelles are attached to the ER?
ribosomes
What are unattached ribosomes in the cytosol called?
Free ribosomes.
What are the differences between prokaryotic ribosomes and eukaryotic ribosomes?
Prokaryotic ribosomes are smaller (70S) compared to eukaryotic ribosomes (80S). Prokaryotic ribosomes consist of a 30S and a 50S subunit, while eukaryotic ribosomes consist of a 40S and a 60S subunit. Prokaryotic ribosomes have fewer proteins compared to eukaryotic ribosomes.
