Default If the codon AAA is changed to UAA,?
If the codon AAA is changed to UAA, it no longer codes for an amino acid; instead, it becomes a stop codon that signals translation termination in a protein. This is an example of a















a silent mutation.















b gross mutation.















c missense mutation.















d nonsense mutation.















e frameshift mutation.

Default
It is a gross mutation - all of the gene beyond the new stop codon is amputated. Silent mutations occur when the codon still codes for the same amino acid; frameshift mutations occur when base pair insertions or deletions cause the read frame to shift.
