What would happen if a mutation occurred in DNA such that the second codon of the resulting mRNA was changed from UGG to UAG?
A) Translation would continue and the second amino acid would be the same.
B) Nothing; the ribosome would skip that codon, and translation would continue.
C) Translation would continue, but the reading frame of the ribosome would be shifted.
D) Translation would stop at the second codon, and no functional protein would be made.
E) Translation would continue, but the second amino acid in the protein would be different.

The codon UAG is a stop codon, which signals the end of the protein sequence. Therefore, if this mutation occurred, translation would stop at the second codon and no functional protein would be made.
