A mutation is found in a tRNA-encoding gene. The wild type allele produces a tRNA that recognizes the codon GAA, and is charged with the amino acid Glutamic acid. The mutant tRNA is still charged with Glu, but the anticodon is mutated such that it recognizes the stop codon TAA. What effect will this have on translation in these cells? Select all that apply In the mutant cells, the stop codon TAA will always be bound by the release factors In the mutant cells, some of the synthesized proteins will be longer. O In the mutant cells, the stop codon TAA will sometimes be bound by the mutant TRNA charged with Glutamic acid. O In the mutant cells, some of the synthesized proteins will be shorter.
