Acylhomoserine lactones used in quorum sensing regulate their own synthesis by an autoinduction system.
- Numerous bacteria use acyl homoserine lactones (acyl-HSLs), significant intercellular signaling molecules, to track the density of their population for quorum-sensing control of gene expression. The LuxI family of proteins produces the signals in question.
- A lot of proteobacteria use quorum-sensing signals from acyl-homoserine lactones.
- Cells create a baseline amount of signal at low population densities, and when enough signal has accumulated in the environment, it binds to its receptor and activates quorum-sensing-dependent genes.

Explanation:
the process of natural selection involves selecting the best of pre-existing traits as needed over time.
Explanation:
Basically, lac operon is an enzyme, and enzymes work in a very well known way called lock key system
. This lock key system works pretty simply, imagine the lock as the enzyme, and this lock needs a specific key to open it, thinking about an enzyme, it needs the specific substrate to breakdown the lactose, this enzyme is called lactase, and it's present in some animals and bacterium too. This doesn't only work for lactose, it's the same lock system for every enzyme, all of them need specific substrate to break it down into things that the body can use for many things.
