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 ...

Once messenger RNA (mRNA) has done its job - conveying the information to produce the proteins necessary for a cell to function - it is no longer required and is degraded. Scientists have long thought that the decay started ...
