The formation of neural tube and neural crest cells. Concept introduction: Neural tube is an embryonic structure which is found in the vertebrate embryo. These neural tubes can ultimately form the brain and spinal cord. The neural tube is formed by a process called neurulation. Neural crest cells are a group of cells which are originated at the dorsal most region of the neural tube. The neural crest cells can migrate to give rise to a number of differentiated cell types. These include the neurons, bone, pigment cells, facial skeleton, cartilage, glia, peripheral nervous system and facial skeleton.

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
