/ˈkəʊdɒn/
noun
1.
(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

1962, from code (n.) + -on.

codon co·don (kō’dŏn’)
n.
A sequence of three adjacent nucleotides constituting the genetic code that specifies the insertion of an amino acid in a specific structural position in a polypeptide chain during the synthesis of proteins.
codon
(kō’dŏn’)
A sequence of three adjacent nucleotides on a strand of a nucleic acid (such as DNA) that constitutes the genetic code for a specific amino acid that is to be added to a polypeptide chain during protein synthesis. Some amino acids are coded for by more than one codon, and some codons do not signal a particular amino acid but rather signal a stop to protein synthesis.
codon [(koh-don)]

A group of three bases on the DNA molecule. Each codon determines the identity of one amino acid in proteins made by the cell.
