Ribosomes are the sites in a cell in which protein synthesis takes place. Cells have many ribosomes, and the exact number depends on how active a particular cell is in synthesizing proteins.

During translation, ribosomes can pause on the nucleic acid. Researchers showed that collisions from incoming proteins get them moving again. Shelby is an assistant editor for The Scientist. She ...

Ribosomal RNA is often modified with chemical tags that can alter the shape and function of the ribosome. Cells use these tags to fine tune protein production. The study found that, in response to ...

This, they write in the study, may mean that the proteins prepared by these ribosomes obtain different shapes than those synthesized by the ribosomes of other cells. “Our study provides the first ...

Ribosomes getting stuck The team also made an important discovery about ribosome collisions—where one ribosome runs into another due to a tricky RNA segment or differences in speed, for example ...

The methyl group, they found, physically blocks the binding site, but it also changes the shape of the ribosome's inner "guts," further disrupting antibiotic activity. Polikanov's laboratory then ...

tRNAs function at specific sites in the ribosome during translation ... folded structure with three hairpin loops that form the shape of a three-leafed clover. One of these hairpin loops contains ...

The newly formed strand of mRNA is now ready to leave the nucleus and travel to the ribosome. After translation, the polypeptide is finally folded into the correct shape and becomes a protein.
