Which of the following is a non-sense codon?

Explanation

In Genetics, a three-nucleotide sequence of mRNA is called a codon. Codons are of two types— Sense codons: These are codons for amino acids and are responsible for protein formation. Their total number is 61. Nonsense (stop) codons: These indicate the termination of protein synthesis. In the standard genetic code, three major stop (nonsense) codons are accepted. These give the termination signal for protein synthesis— UAA (ochre), UAG (amber), and UGA (opal) Therefore, among the given options, only UAA is a nonsense (stop) codon. The remaining are sense codons.
