Exercise 23.6 The two sides of the DNA double helix are connected by pairs of bases (adenine, thymine, cytosine, and guanine). Because of the geometric shape of these molecules, adenine bonds with thymine and cytosine bonds with guanine. The figure shows the thymine- adenine bond. Each charge shown is te and the H N distance is 0.110 nm. (Figure 1) Figure 1 of 1 > k 0.280 Onm Thymine Adenine k 0300 N) Part B Compare this energy with the...
