Watson and Crick hydrogen bonding concept is used in this question. According to Watson and Crick, hydrogen bonding occurs between complementary nitrogen bases. Between adenine and thymine, there exist two hydrogen bonds. Between cytosine and guanine, there exist three hydrogen bonds.
DNA (deoxyribonucleic acid) is a nucleic acid, which is a polynucleotide. It contains nitrogen bases, deoxyribose sugar, and phosphate group. The nitrogen bases are pyrimidines and purines. The purines consist of guanine and adenine, while the pyrimidines consist of cytosine and thymine.
The hydrogen bonding between adenine and thymine would appear as follows:
The hydrogen bonding between cytosine and guanine would appear as follows:
The hydrogen bonding between adenine and thymine would appear as follows:
The hydrogen bonding between cytosine and guanine would appear as follows:

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...

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 (Figure 1) shows the thymine-adenine bond. Each charge shown is ±e, and the H−N distance is 0.110 nm.A) Calculate the net force that thymine exerts on adenine. To keep the calculations fairly simple, yet reasonable, consider only the forces due to the...
