A mutation inserts two nucleotides in the 23rd codon of a bacterial gene encoding a 60-amino acid protein, eliminating the protein function. Which of these additional changes to the mutant gene is most likely to suppress the effect of the first mutation? O Deletion of two nucleotides from the 3rd codon. Insertion of two nucleotides from the corresponding tRNA anticodon. Insertion of a single nucleotide in the 21st codon. O Deletion of a single nucleotide from the 51st codon. Deletion of a single nucleotide from the 24th codon.
