The new DNA codon would be GAT. This would code for the mRNA codon CUA, which would translate into the amino acid leucine. This is a silent mutation because there is no change in the amino acid being coded for at this position, so the polypeptide remains the same. The new DNA codon would be AAG. This would code for the mRNA codon, UUC, which would translate into the amino acid phenylalanine. This would cause a missense mutation, since the amino acid that should be there-valine- gets replaced with phenylalanine. The new DNA codons for the fifth, sixth, seventh, and eighth codons are AAC, CCC, UCC, AA. This results in asparagine, proline, serine and no amino acid as the last four. This is a frameshift mutation so every codon after this is affected. 1. The second DNA codon, CAG, has a substitution in its first nucleotide, with A replacing C. 2. The fifth DNA codon, TGT, has a deletion of the G. 3. The seventh DNA codon, GAG, has a substitution in its third nucleotide, with T replacing G.
