The three stop codons that signal the end of protein synthesis are UAA, UAG, and UGA. Stop codons are crucial in the process of ... Apr 27, 2011 ... These results suggest that 3′ RNA stimulatory structures feature in a much larger proportion of readthrough cases than previously anticipated. In vivo translation termination assays revealed that the Tetrahymena hybrid eRF1 promoted efficient termination at all three stop codons, indicating that eRF1 ... ... three stop codons), in eukaryotes (2–4) (Fig. 1A). However, the mechanism of stop codon recognition by release factors is unknown and represents a long ... In molecular biology, a stop codon (or termination codon) is a codon that signals the termination of the translation process of the current protein.
