What are the Naturally Occurring Polymers in Biology?

-DNA: A Complex Molecule that contains Genetics -It has 2 Stands, made from Nucleotides Monomers that Bond via a Polymerisation Reaction. -It has 4 Different Nucleotide Monomers: A for Adenosine G for Guanosine, C for Cytidine and T for Thymidine -Amino Acids also can make Polymers, which are known as Proteins [They are Polyamides- They make Water] -Carbohydrates also make Starch and Cellulose, which again are Polymers
