Which codon is not an indicator of completion of protein synthesis?
UAG
AUG
UAA
UGA
B.
AUG
Stop codon or termination codon is a nucleotide triplet within mRNA that signals a termination of translation. It signals the termination of this process by binding release factors which cause the ribosomal subunits to dissociate, releasing the amino acid chain. There are three stop codons (for RNA/DNA) respectively i.e.,
For DNA :- UAG (amber), UAA (ochre) and UGA (opal)
For RNA :- TAG (amber), TAA (ochre) and TGA (opal).
AUG acts as the strandard start (or initiation) codon for both DNA and RNA respectively.
