* Organic compounds are defined as molecules that contain carbon atoms bonded to hydrogen atoms.

* DNA and RNA are both made up of long chains of nucleotides. Nucleotides, in turn, contain a sugar (deoxyribose for DNA, ribose for RNA), a phosphate group, and a nitrogenous base.

* Carbon and hydrogen are present in both the sugar and the nitrogenous bases of these molecules.

Therefore, due to the presence of carbon and hydrogen, DNA and RNA qualify as organic compounds.
