Summary Introduction

To add:

Life’s history, DNA evidence, Fossil evidence to Pull It Together concept map.

Concept introduction:

Scientists study the history of life in the context of the geologic timescale that divides time into various eons, eras, period and epoch. The Earth formed around 4.6 billion years ago and was very hot at that time. It slowly cooled down to form Earth crust around 4.1 billion years ago. The origin of life became possible only after that. The various events that occurred after the origin of life can be studied through fossil records and molecular data.

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
