Which one is not a stop codon?

Solution
The correct option is C UCA
A codon refers to a sequence of 3 consecutive bases in the mRNA that codes for a specific amino acid or signals the termination of protein synthesis.
A stop codon (nonsense codon) does not specify any amino acid. The presence of a nonsense codon causes termination of protein synthesis due to which it is also known as stop codon.
There are three nonsense codons - amber (UAG), ochre (UAA) and opal (UGA).
UCA is not a nonsense codon as it codes for the amino acid serine.
