The role of hydrophobic interactions in stabilizing the double-stranded DNA has to be discussed. Concept Introduction: The groups which are not present in contact with the aqueous medium (or) which repels the water molecules are said to be hydrophobic in nature. The DNA molecule is made up of nucleotides which consist of Nitrogenous bases, Sugar molecules and Phosphate ions. The Nitrogenous bases are two types: Purines and Pyrimidines. The Purine bases are Adenine and Guanine. The Pyrimidine bases are Cytosine and Thymine. In the formation of the DNA molecule the bases are paired with each other (Purine base with Pyrimidine base). The pairing occurs as A-T and G-C, the Adenine base containing nucleotide is paired with the Thymine base containing nucleotide and Guanine with Cytosine.

b) Certain cyclic compounds are known to be conformationally similar to carbohydrates, although they are not themselves carbohydrates. One example is Compound C shown below, which could be imagined as adopting four possible conformations. In reality, however, only one of these is particularly stable. Circle the conformation you expect to be the most stable, and provide an explanation to justify your choice. For your explanation to be both convincing and correct, it must contain not only words, but also "cartoon" orbital drawings contrasting the four structures.
