Question
There is a group of six or so genes, called luxlux genes, whose gene products are necessary for light formation. Given that these bacterial genes are regulated together, propose a hypothesis for how the genes are organized and regulated.
 
Match the terms in the left column to the appropriate blanks in the sentences on the right. Terms can be used once, more than once, or not at all.

Bacterial cells blank molecules that can be blank by other bacterial cells. Sensing the concentration of such signalling molecules allows bacteria to monitor the local blank of cells, a phenomenon called blank. There is a group of genes in the genome of the described bacterium, called luxgenes, which are organized in an blank. Reaching a certain concentration, molecules involved in this process blank the luxgenes. As a result, the population of the bacteria needs to reach an optimal level to blank the luxgenes and, thus, blank light production.
