The Genetic Code
DNA is read in three-letter chunks called codons. Each codon tells the cell which amino acid to add next when it builds a protein, and the table below is the full dictionary. Click any codon to see its amino acid in the panel on the right, or type a codon or amino-acid name in the search box to highlight matches.
Colors group codons by the class of amino acid they produce.
How to read this table.
Find your codon's first base in the labels on the left, its second base in the labels on top, and its third base inside the cell. Example:
UCA is row U, column C, third sub-row, which gives Serine (Ser, S).
