- noun 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.
from The Century Dictionary.
- noun A small bell.
- noun The bell or flaring mouth of a trumpet.

- noun (Molecular biology) a sequence of three nucleotides in a genome or a DNA or messenger RNA molecule, which specifies the incorporation of one amino acid or is a stop signal, during the biosynthesis of proteins. Codons occur within the protein-coding segments of the DNA or RNA genome of living organisms. The amino acid sequence of proteins synthesized on ribosomes is thus determined by the sequence of the nucleotides in the genome.

-
It is assumed here that this structure is the result of the hierarchical order of the interaction energies of the bases in codon – anticodon recognition.
-
A typical example of a DNA codon is GCC, which encodes the amino acid Alanine.
-
An amino acid encoding codon is absolutely meaningless in isolation.
-
Whereas a digital byte is mostly 8 binary digits, a DNA byte (called a codon) has three digits.
-
In DNA and RNA, individual amino acids are encoded by a set of three bases called a codon.
