A mutation in a DNA sequence causes a base-pair substitution. The resulting mRNA has the triplet AAA, instead of AAG. Using the codon usage table below, what is the change in the protein sequence?

Question

Accepted Answer

There is no change in the protein sequence

Answer

It is a missense mutation (a differnet amino acid is coded for)

Answer

The protein no longer begins with a start codon

Answer

The frameshift changes all downstream amino acids

Answer

It introduces a stop codon (nonsense mutation)
