Built-in Genetic Codes

MEGA contains four commonly used genetic code tables: (1) Standard, (2) Vertebrate mitochondrial, (3) Drosophila mitochondrial, and (4) Yeast mitochondrial as well as 19 others. They can be used as templates to create additional genetic code tables using the Genetic Code Selector. Genetic codes for these four built-in tables in one letter code are given below.
