Chapter 2, Problem 19PDQ

(a)

Summary Introduction

To determine:

That when the crossing over occurs in the first meiotic prophase.

Introduction:

The meiosis is the process of cell division that produces four haploid cells from the single diploid cell. These haploid cells consist of only half the amount of chromosomes that are present in the parental diploid cells. There are two types of meiosis occurs namely meiosis I and meiosis II. The haploid cells produced by this process consists of a unique combination of paternal and maternal chromosomes. This process plays an important role in genetic recombination within species.

(b)

Summary Introduction

To determine:

That when the synapsis occurs in the first meiotic prophase.

The stage of prophase I where the chromosomes are least condensed.

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
