Having solved the first crystal structure of a eukaryotic ribosome, scientists are now getting a new, more detailed look at the machinery that translates the genetic code into proteins in all living ...

While prokaryotic cells do not have membrane-bound structures, they do have distinct cellular regions (Figure 1). In prokaryotic cells, DNA bundles together in a region called the nucleoid. Primitive ...

Protein synthesis by the ribosome can fail for numerous reasons including faulty mRNA, insufficient availability of charged tRNAs and genetic errors. All organisms have evolved mechanisms to recognize ...

Figure 1: Reconstitution of B. subtilis SRP–ribosome complexes. Figure 5: SRP S domain–ribosome interaction at the ribosome exit. Figure 6: SRP Alu-domain interaction with the ribosome. Together, the ...

A new study shows that eukaryotic ribosomes can be modified to respond to antibiotics in the same way that prokaryotic ribosomes do. According to researchers at the University of Illinois Chicago, the ...

Both prokaryotes and eukaryotes respond to the same RNA structure, initiating protein synthesis and thereby defying longstanding expectations. Prokaryotes and eukaryotes, it was long believed, relied ...
