Summary Introduction

To review:

The percentage of reduction in the growth of the chinaberry trees, which were treated with the acid rain.

Introduction:

Acid rain is caused due to air pollution and has pH less than 5.2. Generally, it is produced by emissions of sulfur dioxide (SO2) and nitrogen oxide (NO2), which react with the water molecules in the cloud to produce sulfuric and nitric acids. It damages the leaves of the plants and limits the nutrients that might be available to them. The effects of the acid rain were tested on the two seedlings, which belonged to two different species. The results that were obtained after the experiment are shown in the graph below. It is given that the acid rain has caused a significant reduction in the size of the chinaberry trees. Furthermore, in the graph *** signifies probability value less than 0.001.

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. Mutation 1 Mutation 2
