## Key Concepts

### Design Principles

**Standardization**
- BioBricks: Standardized parts
- RFC standards: Assembly rules
- SBOL: Data exchange format

### Genetic Circuits

```python
# Example: Toggle switch design
class ToggleSwitch:
    """
    Bistable genetic switch.
    """
    def __init__(self):
        self.components = {
            'promoter1': 'Repressor 1',
            'promoter2': 'Repressor 2',
            'repressor1': 'Inhibits promoter2',
            'repressor2': 'Inhibits promoter1'
        }
    
    def states(self):
        return {
            'state_A': 'Repressor1 ON, Repressor2 OFF',
            'state_B': 'Repressor1 OFF, Repressor2 ON'
        }

# Circuit types
circuit_types = {
    'inverter': 'NOT gate',
    'amplifier': 'Signal enhancement',
    'oscillator': 'Repressible gene expression',
    'memory': 'State persistence',
    'logic_gates': 'AND, OR, NAND, NOR'
}
```
