Bioluminescence Is Controlled by the Gene Regulatory Mechanism Called Quorum

Multiple Choice

Bioluminescence is controlled by the gene regulatory mechanism called quorum sensing, wherein the

A) depletion of oxygen is detected by an inducer molecule which activates transcription of the lux operon (genes luxCDABE) .
B) accumulation of an inducer molecule activates transcription of the lux operon (genes luxCDABE) .
C) absence of light activates an inducer molecule which activates transcription of the lux operon (genes luxCDABE) .
D) host tissues produce an autoinducer molecule which activates transcription of the lux operon (genes luxCDABE) .
