Which one of the following pairs of codons is correctly matched with their function or the signal for the particular amino acid?
GUU, GCU - Alanine
UAG, UGA - Stop
AUG, ACG - Start/methionine
UUA, UCA - Leucine
the codons UAA, UAG, and UGA do not code for any amino acids and function as stop terminator codons. Regarding the other options: AUG is the start codon and codes for Methionine, but ACG codes for Threonine; GUU codes for Valine, whereas GCU codes for Alanine; and UUA codes for Leucine, whereas UCA codes for Serine.
