Question
Chapter 17.4, Problem 3QTC
Summary Introduction
To determine:
Which purpose of sleep makes the most sense among the several other ideas presented regarding the purpose of sleep?
Introduction:
Our bodies need sleep in order to preserve proper function as well as health. In fact, our body is planned to sleep each night as a measure of relaxing our bodies and minds. The internal biological clock, as well as the sleep-wake homeostat, is the two different mechanisms, which mostly determine the timing of our transitions from the state of wakefulness to sleep and vice versa.

The diagram below illustrates a quorum sensing pathway from Staphylococcus aureus. Please answer the following questions.
1. Autoinduction is part of the quorum sensing system. Which promoter (P2 or P3) is critical for autoinduction?
2)This staphylococcus aureus grows on human wounds, causing severe infections. You would like to start a clinical trial to treat these wound infections. Please describe:
a) What molecule do you recommend for the trial. Why?
b) Your trial requires that Staphylococcus aureus be isolated from the wound and submitted to genome sequencing before admittance. Why? What are you testing for?
3) If a mutation arises where the Promoter P3 is constitutively active, how would that influence sensitivity to AIP? Please explain your rationale.
4) This pathway is sensitive to bacterial cell density. Describe two separate mutation that would render the pathway active independent of cell density. Briefly explain your rationale.
