Question

What is quorum sensing?

a.The hypothesis that "too clean. is detrimental" to human health

b. When a critical number of microorganisms is reached in a biofilm, and via electrochemical communication, cause organisms in the biofilm to express new phenotypic traits.

c. Communication between cells

d. The ability of microorganisms to sense its environment and move toward or away from different stimuli

e. The expression of a new gene that leads to new physical characteristics

Answer 1

Quorum sensing is a process by which bacteria sense the population density around them via responding to autoinducers. Autoinducers are chemical signals released by bacteria. Cells communicate via autoinducer molecules, and this leads to change in gene expression. Different bacteria colonies grow together in an integrated manner via quorum sensing.

Correct choice should be :

c. Communication between cells.
