Nucleic acids are composed of smaller units called monomers. In the case of nucleic acids, the monomers are nucleotides. A nucleotide consists of three components: a phosphate group, a sugar molecule (either ribose or deoxyribose), and a nitrogenous base. There are five nitrogenous bases that can be found in nucleotides: adenine (A), thymine (T), cytosine (C), guanine (G), and uracil (U).
DNA (deoxyribonucleic acid) contains the bases adenine, thymine, cytosine, and guanine. RNA (ribonucleic acid) contains adenine, uracil, cytosine, and guanine. The main difference between DNA and RNA is that DNA contains thymine while RNA contains uracil.
To summarize, the monomers that make up nucleic acids are nucleotides, which consist of a phosphate group, a sugar molecule, and a nitrogenous base (adenine, thymine/uracil, cytosine, guanine).
