Which of the following is an example of a natural biopolymer?

Step-by-step solution

Biopolymers are polymers produced by living organisms. They contain monomeric units that are covalently bonded to form larger structures. There are three main classes of biopolymers: polynucleotides (such as DNA and RNA), polypeptides (such as proteins), and polysaccharides (such as polymeric carbohydrates like cellulose or starch). Teflon and Nylon are synthetic polymers. Rubber is a natural polymer (polyisoprene) but is generally not classified under the standard biochemical categories of biopolymers (nucleic aci
