Quorum Sensing Relies Upon a Large Cell Population Which Then

Question

Quorum sensing relies upon a large cell population which then turns on transcription.

Accepted Answer

Quorum sensing involves the detection of an accumulation of signaling molecules, which indicates a high cell population density. Once this threshold is reached, the bacteria initiates a gene expression program that is regulated by the signaling molecule. Therefore, quorum sensing requires a large cell population to activate transcription.
