what is one possible reason that mutation 2 leads to the production of normal blood cells rather than sickle- shaped blood cells ? The mRNA codon GAG acts as a stop signal rather than coding for an amino acid. The mRNA codon GAG corresponds to the tRNA molecule that can carry more than one amino acid. The mRNA codon GAG is unreadable and is therefore skipped over during protein synthesis. The mRNA codons GAA and GAG both code for the same amino acid.
