Cultural definitions for codon

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.

Medical definitions for codon

codon

[ 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.

Scientific definitions for codon

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.
