Question

2. What is quorum sensing in bacteria? A. Quorum sensing, is the regulation of gene expression in response to fluctuations in all population density. Quorum sensing bacteria produce and release chemical signal molecules called autoinducers that increase in concentration as a function of cell density. The detection of a minimal threshold stimulatory concentration of an autoinducer leads to an alteration in gene expression. Among the many traits controlled by quorum sensing is the expression of virulence factors by pathogenic bacteria. 50 Paraphrase this answer

Explanation / Answer

Quorum sensing is the ability of bacteria to modify their gene expression in relation to the population density of the bacteria, it works through the secretion of autoinducers, which increases in concentration when the population also increases, the bacteria senses the concentration of the autoinducers and changes its gene expression, for example in virulence factors.
