While there is much commonality, different parts of the tree of life use slightly different genetic codes.
[1] When translating from genome to protein, the use of the correct genetic code is essential.
The translation table list below follows the numbering and designation by NCBI.
[2] Four novel alternative genetic codes were discovered in bacterial genomes by Shulgina and Eddy using their codon assignment software Codetta, and validated by analysis of tRNA anticodons and identity elements;[3] these codes are not currently adopted at NCBI, but are numbered here 34-37, and specified in the table below.
Comparison of alternative translation tables for all codons (using IUPAC amino acid codes): Three translation tables have a peculiar status: Other mechanisms also play a part in protein biosynthesis, such as post-transcriptional modification.
