An MRNA with the Sequence 5'-UGUGUGUG…

question 53

Short Answer

An mRNA with the sequence 5'-UGUGUGUG….-3' codes in a test tube for a polypeptide with the alternating amino acid sequence Cys-Val-Cys-Val-…. You purify charged tRNAs carrying cysteine, whose anticodons bind with the 5'-UGU-3' codon, and you chemically change the cysteine into alanine. If the charged tRNA with the altered amino acid is used in the mixture for a test tube translation (under conditions in which translation does not need to start at an AUG), what polypeptide results from translating 5'-UGUGUGUG….-3'?
