• Systems Biology: Treating cells as electrical networks with signal pathways
• Synthetic Biology: Using organisms to produce useful substances

Historical Context

• Overview of life's evolution from prebiotic world to multicellular organisms
• Importance of lipid bilayers and compartmentalization in early cell evolution
• Evolution of Homo sapiens linked to genetic and sociological developments

Milestones in Genetics and Genomics

• 1950s: Discovery of DNA's double-helix structure
