Explanation:

Nucleic acids (DNA and RNA) have nucleotides as their basic units. Nucleotides consist of a phosphate group, a sugar ring (ribose in RNA or deoxy - ribose in DNA), and one of five nitrogenous bases (adenine, thymine, uracil, guanine, cytosine). Lipids are made of fatty acids and glycerol, carbohydrates are made of monosaccharides, and proteins are made of amino acids.
