During tRNA аminоаcylаtiоn, the aminоacyl tRNA synthatases activate an amino acid in a reaction with [Q9] prior to being added to tRNA?

Yоu hаve discоvered а new life fоrm thаt performs most of the translation and gene expression functions in the same ways as our friend E. coli. You notice, however that there is no RF1, RF2 or RF3 (release factors) encoded in their genome. Curiously, you also see discover there are tRNAs made that possess an anticodon to each of the STOP codons, which do not exist in any other organism. Lastly, you show that all of the polypeptides in these cells end not with the typical amino acid carboxyl group as shown in Panel A, rather they possess a terminus shown in Panel B. What is the mechanism of translation termination in these cells? This will be a comprehensive answer - be sure to provide sufficient information to demonstrate that you understand all of the components that would be necessary in this process. EXTRA CREDIT: Provide the amino acid sequence that precedes the STOP codon in this peptide. (3 points)
