We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

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.
