Which one of the following pairs of codons is correctly matched with their function or the signal for the particular amino acid?
Solution
(d) : $AUG$ codes for methionine and is initiation or start codon which starts the synthesis of polypeptide. $UAA$ (ochre), $UAG$ (amber) and $UGA$ (opal) do not specify any amino acid so they are called termination codons. $CUU, CUC, CUA$ and $CUG$ codes for leucine whereas $GCU, GCC, GCA$ and $GCG$ codes for alanine.
