To tell: Why binary fission generates chains of cocci in some species and cluster of cocci in some other strains. Introduction: Prokaryotes widely exist in three different shapes: spherical (cocci), rod (bacilli), and spiral (spirochetes). An example for a spherical-shaped bacterium is Staphylococcus sp. Staphylococcus is a gram-positive cocci structured as grape-like clusters. If viewed under a microscope, these bacteria appear as round and are clustered together.

Expert Solution & Answer

Explanation of Solution

The prokaryotic cells are arranged in different forms during binary fission. For example, cocci in chains (streptococci) result from the division in one plane and when daughter cells fail to separate. Cocci in irregular or grape-like (staphylococci) arrangement is due to cell division in three planes and daughter cell failing to separate.

Conclusion

The prokaryotic cells exist in different forms (cocci in chain, pairs, and in grape-like structures).

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
