To draw: To color sister chromatids and follow their distribution through mitosis and cytokinesis. Introduction: Cell division is a process where the cells during high nutrition conditions give rise to two daughter cells. The cell division is two types: Mitosis and Meiosis. The mitosis is where the cell divides to form exactly two replicas of itself. The meiosis is reduction division where the cell replicates but the chromosome number reduced by half. In both the cases, there is an involvement of the spindle fiber machinery to pull apart the sister chromatids to the two daughter cells equally from the metaphase plate. During cell division, DNA occurs in condensed form and appears as distinct chromosomes. Each chromosome has two sets of DNA which forms the sister chromatids which are held together at the centromere.

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
