Identify the three symbols, top to bottom

1. AND/ BOTH

3. NOT

2

Define coherent feed forward loop

A turns on B, and both work together to turn on C

3

Define incoherent feed forward loop

A goes turns on C, but also activates B, which inhibts C

4

Define a flip-flop circuit

Two genes (through their products) repress each other. 

5

Define bi-stable switches

A flip flop circuit where triggers are present to repress both of the repressors at alternate times.

6

Define the oscillator switch

A system of three repressors, each which is responsible for repressing one of the other repressors. Results in oscillation.
