A stop codon is a nucleotide sequence in messenger RNA (mRNA) that signals the termination of protein synthesis during translation. When the ribosome encounters a stop codon (UAA, UAG, or UGA), it prompts the release of the newly synthesized polypeptide chain and dissociation of the ribosomal subunits, effectively ending the translation process. This ensures that proteins are synthesized to their correct lengths, as any sequence beyond the stop codon is not translated into amino acids.
