the top three permit cellular communication and to see phenotypes of the cells.
the last one containes genes to allow signal transduction (to other neighbor cells).
\n
Each of the top three operons can respond specificly to a quorum sensing (QSS) and respond by another QSS giving rise to a chain reaction , to all near bacteria.
The figure NĀ¬ā represents the different genetic constructions that we will try to make.
