Process of Elimination
Option B. Hydrolysis – This option is incorrect. The formation of both glycosidic bonds and phosphodiester linkages occurs via a dehydration reaction. A dehydration reaction is the combination of two molecules to form one larger molecule with the loss of water. Hydrolysis is the reaction that breaks glycosidic and phosphodiester bonds. A hydrolysis reaction is the opposite of a hydration reaction. During a hydrolysis reaction, water is added to the bond to separate the molecules, therefore, this option is incorrect.

Option C. There is a chemical interaction between an amino and a carboxyl group – This option is incorrect. The formation of both glycosidic bonds and phosphodiester linkages occurs via a dehydration reaction. A dehydration reaction is the combination of two molecules to form one larger molecule with the loss of water. While dehydration reactions do occur between amino and carboxyl groups (on an amino acid), they occur during the formation of peptide bonds, not glycosidic or phosphodiester. Therefore, this option is incorrect.

Option D. Both can be further classified as alpha or beta bonds – This option is incorrect. Only glycosidic bonds may be classified as beta or alpha bonds depending on the stereochemistry of the OH within the anomeric carbon in its monosaccharide form. This can’t be done with phosphodiester bonds; therefore, this option is incorrect.

Option E. Both experience partial double bond characteristics – This option is incorrect. Peptide bonds form via a dehydration reaction, similar to glycosidic and phosphodiester bonds. Unlike glycosidic and phosphodiester bonds, peptide bonds exhibit a partial double bond character due to resonance. Glycosidic and phosphodiester bonds do not share this characteristic; therefore, this option is incorrect.
