Stop codons are

  • AUG, GUG

  • UAA, UGA, UAG

  • UAC, UGG

  • AGU, AGA, UAC

Solution

B.

UAA, UGA, UAG

UAG, UAA, UGA are three stop codons or non- sense codons. They do not code for any amino acid.

AUG works as an initiation codon in both prokaryotes and eukaryotes. In rare cases, GUG is used as an initiation codon in bacterial protein synthesis.

AUG is used to code for tyrosine, UGG codes for tryptophan, AGU codes for serine and AGA codes for argenine.
