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.
Best Answer: Naturally occurring polymers include rubber and amber. A polymer molecule has a high molecular mass and is comprised of many smaller, repeating subunits or monomers.Polymers may be found in nature, such as the DNA and proteins found in living cells, or created in laboratories or factories.Polymer molecules come in many shapes and sizes. polymer molecule has a high molecular mass and is comprised of many smaller, repeating subunits or monomers.
