Nucleotide Bonding. A DNA molecule is composed of four smaller nucleotide molecules. Adenine (A) and Thymine (T) are complementary, that is they are capable of forming an electrostatic bond due to the molecular shape. Cytosine

and Guanine

are also capable of forming electrostatic bonds. The C-G bond is shown below. Only ions participate in the bonding. For example, the nitrogen is indicated with a minus sign meaning that it is negatively charged. The charges on each ion are Nitrogen:

Oxygen:

Hydrogen:

Carbon:

Given the distances shown below, with the additional information that the

bond length is

, find the electrostatic force between the Cytosine and the Guanine ignoring the very small contribution from carbon. Is the force attractive or repulsive? How do you know?
