उत्तर
The transcribed mRNA sequence for the DNA strand GAT CAT ACT is CUA GUA UGA.
The name of the last codon is UGA; this is known as a Stop Codon (specifically called the Opal codon).
Its role is to signal the termination of translation. It does not code for any amino acid; instead, it recruits release factors that instruct the ribosome to stop protein synthesis and release the completed polypeptide chain.
