what is the monomer of nucleic acids

The monomer of nucleic acids is called a nucleotide. Nucleotides are the building blocks of nucleic acids, such as DNA and RNA. They consist of a nitrogenous base (adenine, thymine, guanine, cytosine, or uracil in the case of RNA), a sugar (deoxyribose in DNA and ribose in RNA), and a phosphate group.
