C)ester bond
D)ionic bond
E)disulfide bond

Question

Quizplus · Accepted Answer

The covalent linkage between the monomers in a dinucleotide is a phosphodiester bond. This bond connects the phosphate group of one nucleotide to the sugar group of the next nucleotide, creating the backbone of the DNA and RNA molecules. Peptide bonds connect amino acids in proteins, ester bonds connect fatty acids to glycerol in lipids, ionic bonds involve a transfer of electrons between atoms, and disulfide bonds involve the oxidation of sulfhydryl groups in cysteine residues of proteins.
