trinucleotide sequence (UAA, UGA, or UAG) that specifies the end of translation or transcription. Compare: amber codon, ochre codon, umber codon.
See stop codon.
a three-nucleotide sequence (UAA, UAG, or UGA) in messenger RNA that specifies the end of the sequence of amino acids in a polypeptide.

termination codonSee STOP CODON.
termination codonsee NONSENSE CODON.
a triplet in a chain of nucleic acids in mRNA that specifies the order in which amino acids are added. The codon triplet pairs with a sequence of three complementary nucleotides, called the anticodon, present in the anticodon arm of tRNA. Called also triplet. See also deoxyribonucleic acid.
see initiation codon.
three codons, UAG, UAA and UGA, also referred to as amber, ochre and opal codons, in mRNA which terminate translation.
see stop codons (above).
