Open in App
Solution
The correct option is B uracil
Genetic code is unambiguous. One codon specifies only one amino acid and not any other. There are 64 codons. Out of 64, 3 are stop codons or nonsense codons, i.e., these do not code for any amino acid and rest 61 code for one of the 20 amino acids.
UAA (ochre), UAG (amber) and UGA (opal) do not specify any amino acid so they are called termination codons or stop codons. All these codons have uracil as their first base.
