The importance of genetic recombination and post recombination events related to diversity in antibodies Concept introduction: Antibodies are the potential receptors that can recognize unique aspects of antigen present on the pathogen. Antibodies are produced by the differentiation of B cells into plasma cells. Based on the physical, chemical, and immunological properties, antibodies are classified into 5 classes namely IgG, IgA, IgM, IgE, and IgA. All the antibodies share a common structural similarity by having 2 light and 2 heavy chains. Each light and heavy chain are further classified into “constant (C) and variable (V) domains”. Disulphide bonds connect one light chain with another heavy chain. Each heavy and light chain is derived from the combination of several gene fragments generated after several events of recombination.

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
