Unlike the rest of the menus present at startup, the contents of the File menu can change based on the topmost window displayed. Depending on the window displayed, the menu may also include save or print options.
The RNA menu holds all modules that are specifically targeted to use with RNA. Some of its modules have counterparts in the DNA menu, while others do not. Those modules that do not have DNA counterparts usually deal with structures or properties unique to RNA.
The DNA menu holds all modules that are specifically targeted to use with DNA. All of its modules have counterparts in the RNA menu.
The Help menu holds two commands, one to open and browse a detailed help manual, and one to display general information about the RNAstructure application.

The toolbar just below the main menu bar holds a group of commonly used commands, including creation of a new sequence and folding of a single strand of RNA.
