Nucleic acids, which include DNA (deoxyribonucleic acid) and RNA (ribonucleic acid), are made from monomers known as nucleotides. Each nucleotide has three components: a 5-carbon sugar, a phosphate group, and a nitrogenous base.If the sugar is deoxyribose, the polymer is DNA.If the sugar is ribose, the polymer is RNA.When sugar and a nitrogenous base get combined they form a nucleotide. Nucleotides are also known as phosphate nucleotides.ach nucleotide has three components: a 5-carbon sugar, a phosphate group, and a nitrogenous base. If the sugar is deoxyribose, the polymer is DNA.
