Molecules → subcellular organisms: viruses

Cells → unicellular organisms: bacteria and protists
Every disease has an underlying molecular cause with an effect on the cellular level

Successful medical Tx address disease on molecular level
Ex: Epilepsy
Defects in neurotransmission on molecular level affect nerves on cellular level
Ex: Cancer
Defects in signal transduction on molecular level result in abnormal cell growth on cellular level
All animals share the same basic principles of organization
--Human, mouse, dog share 99% homology in genes and proteins
--Practically indistinguishable on molecular level
Most animals have special features in their physiology
--features make animals unique on the molecular, cellular, and organismal level
