Triple Population Biobricks

Population 1 AND GATE <a href="http://partsregistry.org/Part:BBa_K876065">BBa_K876065</a>

This part produces the quorom sensing molecule AHL which combined with the quorom sensing molecule Ai-1 activates population 3.

Population 2 AND GATE <a href="http://partsregistry.org/Part:BBa_K876049">BBa_K876049</a>

This part produces the quorom sensing molecule Ai-1 which combined with the quorom sensing molecule AHL activates population 3.

<a href="http://partsregistry.org/Part:BBa_K876066">BBa_K876066</a>

This part gives the output for the AND gate mechanism by being activated through the quorom sensing molecules by population 1 and population 3.

Population 1 oscillator <a href="http://partsregistry.org/Part:BBa_K876047">BBa_K876047</a>

This part produces the quorom sensing molecule AHL which in turn activates Population 2 when the AHL concentration passes a certain threshold.

Population 3 <a href="http://partsregistry.org/Part:BBa_K876057">BBa_K876057</a> & <a href="http://partsregistry.org/Part:BBa_K876060">BBa_K876060</a>

These parts combined forms population 3 which produces CFP after receiving the quorom sensing molecule Ai-1 from population 2.

<a href="http://partsregistry.org/Part:BBa_K876061 ">BBa_K876061 </a>

This part along with plac-LuxR contitutes population 2 which produces RFP and the quorom sensing mulecule Ai-1 after receiving AHl molecules from Population 1.
