A set of three nucleotides in a protein coding sequence that specifies individual amino acids or a termination signal (codon, terminator). Most codons are universal, but some organisms do not produce the transfer RNAs (RNA, transfer) complementary to all codons. These codons are referred to as unassigned codons (codons, nonsense).
Triplet sequence of bases adenine, cytosine, guanine, thymine (A, C, G or T) which encode a specific amino acid used during translation of mRNAs.
A triplet of nucleotides [three nucleic acid units (residues) in a row] that code for an amino acid (triplet code) or a termination signal.
A three-nucleotide unit that represents the code for the production of a specific amino acid in the process of protein synthesis.
A sequence of three bases (triplet) which specifies a particular amino acid in the sequence of reactions which comprise protein synthesis. The codons of the messenger RNA are matched by the anticodon of the transfer RNA, which brings the amino acids to the ribosome for incorporation into the protein being synthesized.
Code for a specific amino acid, formed of three successive bases in a DNA (deoxyribonucleic acid) molecule.
The unit of the genetic code that determines the synthesis of one particular amino acid. Each codon consists of a section of the DNA molecule, and the order of the codons along the molecule determines the order of amino acids in each protein made in the cell.
A sequence of three bases in a strand of DNA or mRNA (messenger RNA) that is the genetic code for a specific amino acid.
