codon
co·don C0452900 (kō′dŏn′)n. A sequence of three adjacent nucleotides constituting the genetic code that determines the insertion of a specific amino acid in a polypeptide chain during protein synthesis or the signal to stop protein synthesis.
[cod(e) + -on.]codon (ˈkəʊdɒn) n1. (Genetics) genetics biochem a unit that consists of three adjacent bases on a DNA molecule and that determines the position of a specific amino acid in a protein molecule during protein synthesis2. (Biochemistry) genetics biochem a unit that consists of three adjacent bases on a DNA molecule and that determines the position of a specific amino acid in a protein molecule during protein synthesis[C20: from code + -on]co•don (ˈkoʊ dɒn)
n. a triplet of adjacent nucleotides in the messenger RNA chain that codes for a specific amino acid in the synthesis of a protein molecule. Compare anticodon. [1960–65; code + -on1] Thesaurus| Noun | 1. | codon - a specific sequence of three adjacent nucleotides on a strand of DNA or RNA that specifies the genetic code information for synthesizing a particular amino acidsequence - serial arrangement in which things follow in logical order or a recurrent pattern; "the sequence of names was alphabetical"; "he invented a technique to determine the sequence of base pairs in DNA" |

codon: see nucleic acidnucleic acid,
any of a group of organic substances found in the chromosomes of living cells and viruses that play a central role in the storage and replication of hereditary information and in the expression of this information through protein synthesis.

A codon is a unit of the genetic code by means of which all the genetic information is “recorded” in DNA and RNA molecules. Many amino acids have more than one codon (so-called degeneracy of the code). There are three codons which do not code amino acids; rather, they determine the beginning or end of the synthesis of a polypeptide chain. codon[′kō‚dän] (genetics) The basic unit of the genetic code, comprising sequential, nonoverlapping three-nucleotide sequences in messenger ribonucleic acid, each of which is translated into one amino acid; 61 of the 64 codons code for a specific protein synthesis; the other 3 are stop codons that specify termination of the growing polypeptide or protein chain. codon
codon [ko´don] a series of three adjacent bases in one polynucleotide chain of a DNA or RNA molecule, which codes for a specific amino acid.co·don (kō'don), A set of three consecutive nucleotides in a strand of DNA or RNA that provides the genetic information to code for a specific amino acid that will be incorporated into a protein chain or serve as a termination signal.

Synonym(s): triplet (3) . [code + -on]codon A sequence of three consecutive nucleotides (a triplet) along a strand of DNA or messenger RNA that specifies a particular AMINO ACID or a stop signal during protein synthesis. The order of the codons along the DNA molecule determines the sequence of particular amino acids in the protein produced.codon or triplet a group of three DNA nucleotide bases that codes for a specific amino acid in the related protein. see PROTEIN SYNTHESIS, GENETIC CODE.codon
