The tour starts with the <scene name='72/725869/A-rna_overview/1'>Default</scene> view. Now look at this <scene name='72/725869/Rna_space_filling_view/2'>space filling view</scene>.The backbone is yellow and the bases are magenta. Note that the major groove (at the top, when you have just clicked the button) is very deep. | The tour starts with the <scene name='72/725869/A-rna_overview/1'>Default</scene> view.
