The two different mutations which would result in a uvrA constitutive phenotype and mention the actual genotypes involved. Introduction: Mutation is the process of changes at the genetic level in which the coding of the DNA is altered by the chemical, radiation, and environmental factors. These factors are termed as mutagens. Mutagens are capable to induce mutation in an individual.

Summary Introduction

To describe: The outlined series of a genetic experiment that makes use of diploid strains for the determination of the possible mutations that have been isolated.

Introduction: Mutations are the changes in the sequence of DNA which may be harmful or useful for an individual. It leads to evolution and the better survival of an individual. The mutations can be inherited or acquired.

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
