Cys-tRNACYS (Cys-charged tRNACys) can be converted to Ala-TRNACys (Ala-charged tRNACY5) by catalytic reduction. Assume that Ala-tRNA CYS is added into a functional in vitro translation system that contains all the essential components for translation, including: ribosomes, all tRNAs excluding tRNACys, all amino acids, mRNA encoding for a given protein, and all other essential cofactors / enzymes required for translation. Where in the newly synthesized protein would Ala be incorporated? a. at the positions where Ala-Cys dipeptides normally occur for this protein b. at the positions where Ala and Cys normally occur for this protein c. Ala won't be incorporated, because Ala-tRNACys won't be recognized by the ribosome d. at the positions where Ala normally occurs for this protein e. at the positions where Cys normally occurs for this protein
