1.3 Chemistry Is The Central Science.

Although Watson, Crick and Franklin used all branches of chemistry in their discovery (for example Franklin was an expert analytical chemist, relying on x-ray crystallography), they were acting as biochemists when they determined a molecule common to all living things.

long repeating chains of molecules are known as polymers, commonly known as plastics. They are usually organic, such as nylon or polypropylene. Natural sources include rubber and cellulose for example.

chemistry is the entral science. ore basic, foundational, prerequisite fields include math and physics. More applied fields include biology and the social sciences such as psychology and anthropology
