Selecting Biological Fragments
Use the various fields in this window to select amino acids and DNA bases.
The Type field allows you to select either Amino Acid or Nucleoside. When Amino Acid is selected, the left popup menu below the Type field can be used to select the desired amino acid, and the right popup menu in that line allows you to specify the structural form as Central Fragment, Amino-Terminal Fragment, or Carboxyl-Terminal Fragment (the last two are the N-terminated and C-terminated forms, respectively).
When the Type field is set to Nucleoside, the left popup menu below the Type field can be used to select the desired DNA base (nucleic acid fragment), and the right popup menu in that line allows you to specify the structural form as Central Fragment, C3’-Terminal Fragment, C5’-Terminal Fragment, or Free Nucleoside.
The various palettes in GaussView can be used in a modal (dialog box
behavior) or amodal (floating palette behavior) manner. The thumbtack
icon in the upper left corner of the window shows whether the palette
will close when another one is selected (or a non-building context is
entered). The green pushed-in tack indicates that the palette is
“tacked” to the desktop (i.e., “sticky”): 
; the red
upward-pointing tack similarly indicates close-on-use behavior:
