Synthetic Biology What is Synthetic Biology? It is an emerging field of biology that aims at designing and building novel biological systems. The final goal is to be able to design biological systems in the same way engineers design electronic or mechanical systems.
Synthetic Biology Why do we need it? “What I cannot create, I do not understand.” - Richard Feynman
Synthetic Biology Why do we need it? Cells are the ultimate Chemical Factory.
Synthetic Biology Is it achievable? 1- Biology is hierarchical
Synthetic Biology Is it achievable? 2- Biology is Modular
Synthetic Biology Is it achievable? Hierarchy and Modular (recurrent) organization allows biology to be understandable and synthetic biology to be possible.
Synthetic Biology A possible hierarchy for synthetic biology
Synthetic Biology Biological Components: 1-Parts
Synthetic Biology Biological Components: 2-Devices
Synthetic Biology Biological Components: 3-Systems or Modules

Synthetic Biology Synthetic Biology as Engineering For synthetic biology to become a form of engineering it will be necessary to achieve precision and reliability. Factors preventing this: 1- Incomplete knowledge of biology. 2- Inherent functional overlap (parts with many -some unknown- functions, some of which are detrimental to the goal in mind. 3- Incompatibility between parts. 4- Parts functionality depends on context. 2- CI represses expression of unrelated host genes 3- LuxR interacts with CI and blocks its function 4- GFP is non-fluorescent in host
Synthetic Biology Parts should not have multiple functions (One subunit of T7 phage DNA polymerase is actually E. coli thioredoxin) Parts should not encode multiple functions Synthetic Biology as Engineering Standard Parts
Synthetic Biology Different parts should be compatible Parts should work in different contexts Synthetic Biology as Engineering Standard Parts
Synthetic Biology Synthetic Biology as Engineering Standard Parts Standardized parts could be easily exchanged between different devices (as well as between different laboratories)
