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.
1 Monomer: A small molecule that bonds to other molecules to form a polymer. 2  Nucleic Acids: A group of organic macromolecules that are made of nucleotides. 3  Contain hydrogen, oxygen, carbon, and phosphorus. 4  Examples are RNA, DNA, and ATP. Polymer: A large molecule made up of many repeating structural units called monomers. 2  Polymerization: Process that forms a large molecule (polymer) from repeating subunit molecules (monomers). 3  Polypeptide: A chain of up to 100 amino acids.
