Codon Meaning and Definition in Wikipedia


The genetic code is the set of rules by which information encoded within genetic material (DNA or mRNA sequences) is translated into proteins by living cells. Biological decoding is done by the ribosome. This links amino acids together in an order specified by mRNA. It uses transfer RNA (tRNA) molecules to carry amino acids and to read the mRNA. The molecules read the mRNA three nucleotides at a time. These nucleotide triplets are called codons. A codon specifies which amino acid will be added next during protein synthesis. There are some exceptions, but usually a three-nucleotide codon represents a single amino acid.

The genetic code among all organisms is very similar. It can be expressed in a simple table with 64 entries.
