What monomers make up DNA and RNA?amino acidsnucleic acidsphosphoric acids

The monomers that make up DNA and RNA are nucleic acids. These nucleic acids are composed of three parts: a five-carbon sugar, a phosphate group, and a nitrogenous base. In DNA, the sugar is deoxyribose and the nitrogenous bases can be adenine (A), thymine (T), guanine (G), or cytosine (C). In RNA, the sugar is ribose and the nitrogenous bases can be adenine (A), uracil (U), guanine (G), or cytosine (C). Amino acids are the monomers for proteins, not for DNA or RNA. Phosphoric acids are part of the structure of the nucleic acids, but they are not the monomers that make up DNA or RNA.
