Summary Introduction

To determine:

The techniques used in DNA technology by the researchers to reveal the origin of meat.

Introduction:

DNA technology is the study and altering the genetic material of an organism to produce a new trait. The technology is useful in producing the pest resistance crops, highly nutritional food and so on. DNA technology consists of various techniques like Recombinant DNA technology, Gene therapy, DNA fingerprinting, DNA microarray technique and many more.

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
