Programming in BE
Abstract concepts
- Abstraction hierarchy: high to low
- Decouling: breaking a complex system down
Comparison of Python and Biology
Python
- Functions
- Classes
- Inheritance
- Instances
- Passing data
Biology
- DNA
- TAATA, etc.
- Parts
- Basic biological function encoded in DNA
- Devices
- One or more parts that encode a human-defined function
- Systems
- One or more devices that perform a human-defined function
Recall that for an example of a genetic device, we spent a bunch of time making genetically encoded inverters, where one protein controls the operator of another protein. (see figure)
Protein kinases
(figure) Protein kinase B phosphorylates protein kinase C to prevent it from phosphorylating something else. Is this a good device?
- No. Signal is specific. PEpS not interchangeable. Need common signal carrier.
How can you fix it?
- ???
Can you describe a biological function that you can use without worrying about the details?
