Solution

Yes, with the recent researches, dual functions of other codons besides AUG have been discovered. It has been shown that stop codons; UGA and UAG code for additionally discovered amino acids selenocysteine and pyrrolysine respectively in competition with translation termination. In 1989, it was found that a CUG which is an universal leucine codon also codes for serine. Thus, ambiguous meaning of CUG has been discovered.
