Quorum Sensing: ability of some bacteria to change phenotype at different population densities
phenotypes-observed characteristics in an orgainism
genotype-the set of traits they have genetic information for
in quorum sensing there are many different types of bacteria that have genes that are not always expressed or are only expressed under some conditions
Ex:Suicide at high population densities
Strep. pneumoniae- genes for signal receptors always on when all receptors have signal molecule another gene, LytA gene, is expressed-death of bacteria
