Now the bases are easier to see. Notice how they are stacked upon each other and are nearly perpendicular to the axis of the double helix. Note also that the backbone forms a smooth, continuous curve. | Now change the display to make it show the <scene name='72/725442/Space_filling_bbone/2'>sugar-phosphate backbone as pseudo-bonds</scene> connecting the phosphate atoms.
