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.
See also: genetic code.
Synonym(s): triplet (3)
[code + -on]

codon

/co·don/ (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.

codon

(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.

codon

[kō′don]
a unit of three adjacent nucleotides along a DNA or messenger RNA molecule that designates a specific amino acid to be incorporated into a polypeptide. The order of the codons along the DNA or messenger RNA determines the sequence of the amino acids in the polypeptide. Also called trinucleotide. See also anticodon, genetic code.

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

sequence of three nucleotides in DNA or RNA, coding for an amino acid

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.

start codon
see initiation codon.
stop c's
three codons, UAG, UAA and UGA, also referred to as amber, ochre and opal codons, in mRNA which terminate translation.
termination codon
see stop codons (above).

Initiation occurs when the ribosome binds the start codon in mRNA (AUG) with the amino acid methionine.
The traditional approach to producing more tRNAs would have been to change the anticodons of existing ones, giving rise to a new class of amino acids proliferating across the code while systematically reshuffling a large number of codons in the process.
