Question
Chapter 11.4, Problem 4MC
Summary Introduction
To analyze:
The description of CRISPR-Cas used to modify specific genes.
Introduction:
Clustered regularly interspaced short palindromic repeats is the abbreviation for CRISPR. Both bacteria and archaea have this often found in their DNA sequence. These are likewise produced from bacteriophage and DNA fragments. They are used to identify shared DNA during infections.

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.
