Both dna and rna nucleotides contain three basic components. nucleotides contain all of the components listed except

Sugar - Either ribose or deoxyribose (in RNA or DNA)
Nitrogenous base - Adenine, guanine, cytosine, thymine (only in DNA), uracil (only in RNA)
Phosphates - One to three, two of which are usually hydrolyzed to provide the energy to attach the nucleotide and form the phosphodiester bond

Molecules called lipids have long hydrocarbon chains that determine the way they act. they can be fats, oils, or hormones, and even exist in our cell membranes
