Polymers are giant molecules , long sequences of chemical units bonded together.
Proteins consist of a sequence of amino acids of a predetermined length and sequence, DNA and RNA consist of phosphate backbones with predetermined sequences of four nucleic acids. Used with permission. Addition polymers form by adding one small molecule, the monomer, to the end of a forming chain of monomer units. Natural rubber and polyethylene are addition polymers. Condensation polymers form in a series of condensation reactions in which two molecules react with the elimination of a small molecule such as water.
