The genetic code was once believed to be universal: [20] a codon would code for the same amino acid regardless of the organism or source. However, it is now agreed that the genetic code evolves, [21] resulting in discrepancies in how a codon is translated depending on the genetic source.
In particular, the genetic code clusters certain amino acid assignments. Amino acids that share the same biosynthetic pathway tend to have the same first base in their codons. This could be an evolutionary relic of an early, simpler genetic code with fewer amino acids that later evolved to code a larger set of amino acids. [84]

This is the standard or universal genetic code. This table is found in both DNA Codon Table and Genetic Code (And probably a few other places), so I'm pulling it out so it can be common. By default it's the DNA code (using the letter T for Thymine ); use template parameter "T=U" to make it the RNA code (using U for Uracil ).
This is the standard genetic code (NCBI table 1), in amino acid→codon form. By default it is the DNA code; for the RNA code (using Uracil rather than Thymine), add template parameter "T=U". Also listed are the compressed codon forme, using IUPAC nucleic acid notation. It's referenced in a couple of places, so have a single master copy.
