Table 1 shows the genetic code of the messenger ribonucleic acid (mRNA), i.e. it shows all 64 possible combinations of codons composed of three nucleotide bases (tri-nucleotide units) that specify amino acids during protein assembling.

For mRNA there are 4 3 = 64 different nucleotide combinations possible with a triplet codon of three nucleotides. All 64 possible combinations are shown in Table 1. However, not all 64 codons of the genetic code specify a single amino acid during translation.

Note that there are 3 additional codons for chain termination, i.e. there are 64 DNA (and thus 64 different mRNA) codons, but only 61 of them specify amino acids. Table 5 shows the genetic code for the translation of all 64 DNA codons, starting from DNA over mRNA and tRNA to amino acid.

The genetic code is a system of specific base sequences that specify which amino acids are to be used for the synthesis of a protein during translation. The genetic code is comprised of codons which consist of a triplet of bases and specify a specific amino acid.

Table 5 shows the genetic code for the translation of all 64 DNA codons, starting from DNA over mRNA and tRNA to amino acid. In the last column, the table shows the different tRNA anticodons minimally necessary to translate all DNA codons into amino acids and sums up the number in the final row.

The genetic code can be expressed as either RNA codons or DNA codons. RNA codons occur in messenger RNA (mRNA) and are the codons that are actually read during the synthesis of polypeptides (the process called translation).

There are 64 codon sequences, sixty-one specify amino acids and three direct the termination of translation. Since there are 20 naturally occurring amino acids more than one codon can specify an amino acid. For example, isoleucine is specified by three codons AUU, AUC and AUA.

Amino Acid Translation Table. Use this table to translate an mRNA code into an amino acid sequence. 1) Locate the first nitrogenous base (A, U, C, or G) of the codon you are translating. Then match it with the First Letter row of the table [large shaded white (A or C) or salmon (U or G) rows].

While it is not possible to predict a specific DNA codon from an amino acid, DNA codons can be decoded unambiguously into amino acids. The reason is that there are 61 different DNA (and mRNA) codons specifying only 20 amino acids.

A carboxylic acid in which an amine group is bonded to the carbon atom neighboring the carboxyl group. Triplets of DNA bases code for individual amino acids.

Isoleucine is an AUU amino acid.
