A codon substitution changes the mRNA from CCA to CCG. A codon chart lists both codons as proline. Which interpretation is strongest?
A
The mutation changes proline to glycine because any G in a codon means glycine.
B
The mutation creates a frameshift because one base was replaced.
C
The mutation is synonymous at the amino acid level because both codons map to proline.
D
The mutation proves that codons are read as pairs instead of triplets.
