• Abstraction -- a term borrowed from software engineering to indicate the management of complexity inherent to biological parts and the systems made with them. Abstraction simplifies components by hiding, or "black boxing" information, facilitating their use and re-use

Standardization
a series of assembly andcharacterization rules. In time, thesestandards may allow the reliablephysical and functional assembly ofgenetic parts into devices, anddevices into systems

• What precisely is the problem or opportunity you are focusing on?
• How clear are you on an approach to make a dent in the problem?
• What if your project is fully successful? How big a difference could it make? What concerns will it raise?
• What other technologies can be used/have been used to address this area?
• What don't you know? How big are the gaps in what you know? How much is completely unknown or unknowable?

•iTune: the test part of the paradigm
•Characterizing the device
•Can we tune it to the output we want?
•Why would we want to do this?

• We can increase or decrease the output of a gene by affecting:
• The promoter• Which alters the rate of transcription
• The RBS– Which alters the rate of translation
