Summary Introduction
Introduction:
Degeneration of an organ system is called as senescence. Degeneration occurs after the age of highest functional efficiency, such as reduced ability to repair damage, increased susceptibility to disease, gradual loss of reserve capacities, and compensation for stress. Unrepaired damage of the DNA is a leading theory of senescence. Generally, in a mammalian cell, the DNA undergoes a predictable 10,000 to 100,000 damaging events per day. Particularly, the oxidative stress from free radicals produced by the cell’s own

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.
