tRNA help

A single base substitution in the anticodon loop of one of the tRNAs for glycine (tRNAgly) can hypothetically generate a mutant tRNA that is able to suppress translational termination by causing insertion of a glycine residue at certain termination codons.  Such mutant tRNAs are in fact encountered in nature and are referred to as suppressor tRNAs.  Assume that there are multiple tRNAs for glycine (so that this hypothetical mutation would not be lethal) and that one of these tRNAs acquires a single base mutation in its anticodon loop.


A. What is the nucleotide sequence of the wildtype anticodon of tRNAgly (5’-3’ polarity) and what is the mutant sequence that would have the properties described above?
   
B)  At which stop codon(s) would the mutant tRNAgly be able to suppress translational termination?
