1. Naturally Occuring Polymers

   • Deoxyribonucleic Acid (DNA)
   • Other Polymers that you need to know
     • Starch
     • Sugars
     • Function - Stores Energy

2. Monomers

   • Monomers - Neucleotide
     • Structure - 2 Polymer chains formed to create a double helix. 4 Monomers (nucleotides A,C,G and T) join in pairs.
     • Functions - Encodes genetic instructions for the development and function of lving organisms and pathogens.
   • Monomers Cellulose - Sugars
     • Function - Supporting in plant cell walls.

3. Polymerisation Types

   • Condensation
     • 2 Types of monomers with 2 functional groups
     • 2 Products
     • 2 Functional groups which react on each monomer
