How is basic biological and biomedical research done?

• Micro-version: A scientist formulates a non-trivial hypothesis with biological significance and then designs and performs well-controlled experiments to test the hypothesis.
  
  
• Midi-version: The Science Cycle – remove any component and the cycle collapses. Ideas fuel the cycle. Words in parentheses are the equivalents in business.
  
  
• Macro-version: How science progresses.
