A barcode for shredding junk RNA

28 agosto 2015

A growing, dividing cell uses most of its energy store to make its «protein factories,» the ribosomes. An important player in their «assembly» is the exosome, a molecular shredding machine that breaks down excess ribonucleic acid (RNA). Researchers have discovered how the exosome identifies its target RNA. The team identified a specific detection signal, comparable to a postal code or bar code that targets the exosome to the remote RNA.
