Let's start with the base.

Click the button to view the adenine molecule. Then, click on the molecule itself and rotate it around with the mouse to get a feel for its shape. Notice the two rings joined together.

Study Question:

What shape best describes the molecule?

a. The atoms form a football shaped molecule.
b. Most of the atoms of the molecule lie in the same plane.
