4. The following sequence of questions (a-c) illustrates how the
duplication in coding for amino acids can minimize the impact of
point mutations in DNA. For each scenario, show the products (mRNA
codon, tRNA anticodon, and amino acid) for each step of the
process.
a. Which amino acid would be produced if transcription took
place from the DNA sequence CAT?
DNA sequence: C A T
mRNA codon: __________________________
tRNA anticodon: __________________________
amino acid: __________________________
b. If a genetic mistake (a mutation) occurred during replication
and the new DNA strand has the sequence CAG, which amino acid would
result?
DNA sequence: C A G
mRNA codon: __________________________
tRNA anticodon: __________________________
amino acid: __________________________
c. What if the mutation resulted in a DNA strand with the
sequence GAT?
DNA sequence: G A T
mRNA codon: __________________________
tRNA anticodon: __________________________
amino acid: __________________________
