Where are ribosomes produced in a eukaryotic cell?Question:Where are ribosomes produced in a eukaryotic cell?Ribosomes:Every cell, including eukaryotes and prokaryotes, contains ribosomes. They are the site of protein synthesis, also called translation. They have two parts: the large and small su...
Answer to: Ribosomes - are not found in prokaryotes. - carry genetic information. - carry out translation. - contain RNA only. - None of the above...
Ribosome-inactivating proteins (RIPs) are a group of proteins with rRNA N-glycosylase activity that irreversibly inhibit protein synthesis and consequently cause cell death. Recently, an RIP called ledodin has been found in shiitake; it is cytotoxic, strongly inhibits protein synthesis, and shows rRN...
Separation of ribosomes from other cell components depends mainly on centrifugation in an appropriate medium and the classes of particles are often distinguished in terms of their sedimentation constants. After homogenization of a tissue or disruption of cells, the larger components (nuclei, mitochondria...

are similar, and both share the ribosome as the main target, Api88 exhibits a significantly higher uptake rate, resulting in a faster accumulation of the peptide within the cell7,15,16. However, structural and biochemical studies highlighted the importance of the C-terminal carboxylate group in ...

“Pathogens are acquiring resistance faster than we can introduce new antibiotics, and this is causing a human health crisis,” says biochemist Kim Lewis of Line Northeastern University. Lewis is part of a team that recently unveiled a promising antibiotic, born from a new way to tap the ...
Describe the transcription and translation that happens during protein synthesis. Explain the difference between DNA transcription and translation. Where do the ribosomes come in? Are ribosomes involved in DNA replication? Describe the process of DNA replication,...
