Repressors
So far, we've been talking about repressors.
- Can't replace a computer with it, as it isn't quite fast enough.
- Defined NOT, AND, FOR, etc., devices
- Can use sender/receiver devices, not just boolean logic
- Start to think about sensors/actuators, etc.
Characteristics
What do we want to know about the physics/biology of our inverters?
- Toxicity
- Speed
- Signal levels
- Transfer function
- Load placed on cell
Do we care about the relation between the input and the output?
- We care about the range of the input signal
- How the output changes (transfer function)
How are we going to come up with answers?
Let's look at an inverter. Say the repressor controls something called [math]\displaystyle{ \lambda }[/math] cI.
- Model depends on physics of system
- Also going to encounter the science/biology of system
- [math]\displaystyle{ \lambda }[/math] is a phage that does such & such...
- [math]\displaystyle{ \lambda }[/math] repressor doesn't turn off in all instances, blah blah
