The default genetic code can be changed at any time. If an annotated sequence window is open at the time you make the change, any autotranslations that are present will be updated immediately to reflect the new genetic code settings. However, the results of previous analyses will not be changed. For example, if you translate a DNA sequence and create a new protein sequence window, the amino acids in the protein sequence will not change if you subsequently change the genetic code.
1. Choose Options | Modify Genetic Codes.
The Genetic Codes dialog box is displayed.
2. Choose a code from the genetic code drop-down menu.
3. Select OK to remove the Genetic Code dialog box.
