(tRNA) molecules affect the ability of the ribosome to determine and select the correct tRNA in each step of translation. Green's investigations into other aspects of translation quality control have included research into the mechanisms and effects of mRNA surveillance, in which mis-coded or nonfunctional mRNAs are subjected to degradation.
