Nucleic acids are polymers of individual nucleotide monomers. Each nucleotide is composed of three parts: a 5-carbon sugar, a phosphate group, and a nitrogenous base. Only two 5-carbon sugars are found in nature: ribose and deoxyribose.
Yes, nucleic acids do contain nitrogen. Nucleic acids (DNA, RNA) are synthesized by polymerization of nucleotides. Each nucleotide contains a phosphate group, a pentose suga â¦ r, and a purine or pyrimidine base.  It is the bases that contain nitrogen (N).   The nucleotides which make up nucleic acids are composed of the following: a phosphate group (PO4), a deoxyribose sugar (in DNA) or a ribose sugar (in RNA) and finally a nitrogenous base.
