2. Who has heard of….. The Minimal Cell?

3. The Minimal Cell is … Recipient cell: M. capricolum Genome: M. mycoides JCVI-syn1.0 First synthetic self-replicative cell (May 2010) Mother: computer Function of every gene is known (1.8 Mbp) 15 years 24 scientists ~$40 million Chassis for biological devices

4. A Living Factory! What is synthetic biology?

5. Design Hierarchies

6. Arteminisin Project: Anti-malaria drug BioFene: biofuels Terraforming Research: NASA Sensors Bioremediation Applications

7. According to the World Health Organization, each year nearly 500 million people become infected with malaria, and nearly 3 million — mostly children — die from it. Malaria Crisis

8. Drug produced from plant (14 month cycle): $2.40/dose Drug produced from microbe (14 days): $0.25/dose Savings: $2.15/dose X 500 million doses = $1 Billion Arteminisin

21. DNA RNA Protein Replication Transcription Translation Central Dogma of Biology

22. A gene is a region of DNA, corresponding to a unit of inheritance. DNA Protein Many genes produce proteins. RNA Ribosome Binding Site Gene Y Promoter Ribosome Binding Site Gene Y Y Y Transcription Translation Gene Transcription

23. Some genes have the ability to regulate other genes. When placed in the same organism, these genes interact with one another to form a gene network. Gene YGene XGene Z Note that, as pictured, this network has a feedback loop Gene Transcription

24. Activation When one gene or factor induces creation of more of another gene, denoted with an arrow (  ) connecting the two Gene YGene X Gene X is transcribed Repression When one gene or factor prohibits creation of another gene, denoted with a perpendicular symbol (--|) connecting the two Gene YGene X Gene X is not transcribed Gene Transcription

26. Engineering with Synthetic Biology

27. Develop initial scheme for a gene network Test smaller circuits in the network Create mathematical model to understand theoretical behavior Rational Design

28. If indicated, modify theory based upon experimental results Construct and test larger network As with other engineering disciplines, this process requires standardization, modularity, and modeling Tweak as needed/desired Rational Design

US Standard Screw Thread “In this country, no organized attempt has as yet been made to establish any system, each manufacturer having adopted whatever his judgment may have dictated as best, or as most convenient for himself” – William Sellers, Franklin Institute, April 21, 1864 Standardization

35. Enabled by standardization Swap interchangeable parts or units in a particular category to achieve new function Groups of parts define a unique functional unit New unit, new function Modularity

36. Analogy: Upgrading the processor on your computer - All other parts of the computer remain the same, but the computer functions differently. Example: Modular promoters Gene Y Higher output of Y Lower output of Y Promoter 1 Promoter 2 Modularity
