codon | Learn Science at Scitable - Nature Publishing Group : science journals, jobs, and informat
A triplet sequence of DNA or RNA nucleotides corresponding to a specific amino acid or a start/stop signal in translation. ... A codon is a sequence of three DNA or RNA nucleotides that corresponds with a specific amino acid or stop signal during protein

Codon - definition from Biology-Online.org
Single point mutations can lead to differences in binding of miRNAs. On the protein level, there are several options, you can have premature STOP codon and the resulting peptide is too short to do its work. Or you can have change of a crucial residue to t

codon - definition of codon by The Free Dictionary
co·don (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.] codo
