DNA and RNA are made up of?

DNA and RNA are biopolymers composed of nucleic acids. Nucleic acids are made up of 3 things, a carbohydrate (ribose), a nitrogenous base (adenine, thiamine, guanine, cytosine, and uracil), and a phosphoester back bone ( like phosphoric acid, ribose-PO4-ribose). the difference between DNA and RNA is the ribose sugar, for DNA it is missing a OH group on it, thus Deoxyribose Nucleic Acid (DNA), where as a full ribose is used for Ribose Nucleic Acid (RNA).
