Why an encounter of a stop codon is expected about every 20 codons or so in a random sequence of DNA. Concept introduction: According to the genetic code, a stop codon or termination codon is a nucleotide triplet within messenger RNA that signals the termination step in the translation of proteins. Stop codons in eukaryotic organisms are UAG, UGA, and UAA that determine the end of the protein. Out of the 64 codons, these three are only involved in termination process. During protein synthesis, AUG codon acts as the starting codon, and it always codes for the amino acid, methionine. And the amino acid chain, which is elongated to form a protein, stops only after a stop codon.
