Polymers are very large molecules that are composed of many smaller subunits connected together by various types of chemical bonds. Some popular examples are polyethylene, the common plastic used in kitchen sandwich baggies and DNA, the genetic blueprint. Polyethylene is composed of many small ethylene (2 carbons and 4 hydrogens) molecules aligned in a head-to-tail manner and polymerized to form poly methylene groups with methyl groups at each end.
