Question

Use the codon table to determine whether or not this mutation will cause a change in the phenotype of the organism

Answer 1

C. Even though the DNA sequence changed, the sequence still codes for the same amino acid, so no change in phenotype will occur.

Step-by-step explanation:

As there is mutation in DNA sequence from ACG to ACA so after transcription mRNA stand will have Codon UGU instead of UGC.

From the Codon table we can conclude that both UGU & UGC codes for Cys after translation of the mRNa sequence.

So, there would be no phenotypic change in the organism as still the codon sequence will code for same amino acid as before mutation.
