This dialog selects the desired genetic code, and edits and displays the properties of the genetic codes. At present only one genetic code can be selected in MEGA at any given time; it is used for all coding regions in all sequences in the data set.
To select a genetic code, click in the square box to its left.
You can also highlight any genetic code by clicking on the text.
You can then use the following buttons found along the top of the dialog box:

Add |
Creates a new genetic code table. A code table editor will be shown with the genetic code of the currently highlighted code table loaded. |
|
Delete |
Removes the highlighted genetic code from the list. Note that the standard genetic code cannot be deleted. |
|
Edit |
Modifies the highlighted genetic code or its name. The code table editor will be invoked for editing the genetic code. |
|
View |
Displays the highlighted genetic code in a printable format. |

Statistics |
Displays the number of synonymous and non-synonymous sites for the codons of the highlighted genetic code following the Nei-Gojobori (1986) method. The degeneracy values for the first, second, and third codon positions are displayed following Li et al. (1985). |
