The "universal" genetic code is now known to have exceptions. evidence for this can be found if
which of the following is true?
a) if a single mrna molecule is found to translate to more than one polypeptide when there are
two or more aug sites.
b) if one stop codon, such as uga, is found to have a different effect on translation than another
stop codon, such as uaa.
c) if prokaryotic organisms are able to translate a eukaryotic mrna and produce the same
polypeptide.
d) if several codons are found to translate to the same amino acid, such as serine.
e) if uga, usually a stop codon, is found to code for an amino acid such as tryptophan (usually
coded for by ugg only).
