Summary Introduction

To review:

The similarities and differences among transformation, conjugation and transduction.

Introduction:

Genetic recombination is characterized by DNA (deoxyribonucleic acid) transfer in bacteria, from one organism, known as the donor, to another organism, known as the recipient. Such a genetic transfer is also known as horizontal gene transfer. In bacteria, obligate sexual reproduction is not present. Horizontal gene transfer is also known to occur between different species.

Explanation of Solution

The differences between transformation, conjugation and transduction are tabulated below.

Transduction Transformation Conjugation
The transfer of the genes from one bacterium to another is referred to as transduction. The incorporation of exogenous genetic material, resulting in the genetic alteration of a cell, is called transformation. The genetic material transfer among the bacterial species with the help of sex pilus is called conjugation.
It does not require for the occurrence of any physical contact between the recipient and the donor organism. It requires the occurrence of physical contact between the recipient and the donor organism. There is a direct cell-to-cell contact or a bridge-like connection between the two cells.
Resistant to DNase. Not resistant to DNase. Role of DNase is not defined.

The similarities among transformation, conjugation and transduction are as follows:

1. All three, that is, transformation, transduction and conjugation, are examples of horizontal gene transfer as genetic information is not transferred from the parent to the offspring.

2. All three methodsincrease genetic variation as a part of genetic material is transferred from the donor to the recipient.

Conclusion

Therefore, it can be concluded that all three, that is, transformation, transduction and conjugation are methods of transferring genetic material, but they all differ in the process of transfer.

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
