WebbThere are three amino acids encoded by six different codons: serine, leucine, and arginine. Only two amino acids are specified by a single codon each. One of these is the amino-acid methionine, specified by the codon AUG, which also specifies the start of translation; the other is tryptophan, specified by the codon UGG. WebbThe stop codon marks the termination of the translation process. A start codon interacts with initiation factors or nearby sequences to initiate the translation process. A stop codon can individually initiate the termination. The standard start codon is AUG. The standard stop codon is UAG, UGA and UAA. Usually codes for methionine. fast food news articles
