The fruit fly lacks the tRNA nuclear export receptor Exportin-t, which only exports end-processed tRNAs to the cytoplasm to ensure the completion of the processing steps in the nucleus. The related ...

To build proteins, cells rely on a molecule called transfer RNA, or tRNA. tRNAs act like protein-building couriers, where they read the genetic instructions from messenger RNA, mRNA, and deliver the ...

The ribosome, that protein-making machine, relies on other, smaller machines. For example, it works in concert with a mechanism that supplies amino-acid-carrying tRNAs, including tRNAs that require ...
