A) \[\text{AUG,}\,\text{GUG}\]
B) \[\text{UAA,}\,\text{UGA,}\,\text{UAG}\]
C) \[\text{UAC,}\,\text{UGG}\]
D) \[\text{AGU,}\,\text{AGA,}\,\text{UAC}\]
Correct Answer: B
Solution :
Three codons UAG, UAA and UGA are stop codons or nonsense codons. They do not code for any amino acids. AUG works as initiation codon in eukaryotes and prokaryotes. In rare case GUG also serve as initiation codon in bacterial protein synthesis. UAC coded for tyrosine, UGG coded for tryptophan, AGU coded for serine, AGA coded for argenine.
