Expert Solution & Answer

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.

Bacterial conjugation has medical consequences. For example, certain plasmids contain genes that code for toxins. The causative agent of a deadly form of food poisoning, E. coli 0157, synthesizes a toxin that causes massive bloody diarrhea and kidney failure. This toxin is now believed to have originated in Shigella, another bacterium that causes dysentery. Similarly, the growing problem of antibiotic resistance is partly attributable to the spread of antibioticresistant genes among bacterial populations. Antibiotic resistance develops because antibiotics are overused in medical practice and in livestock feeds. Suggest a mechanism by which this extensive use promotes antibiotic resistance.

A hypothetical gene for cephalosporin resistance is found to be carried by a transposon. Explain what a transposon is. Then explain how the cephalosporin resistance could be horizontally transferred between organisms by transformation, conjugation, and transduction. What steps/events would have to occur to allow the transposon to be transferred by each method. Also, explain how it could be transferred vertically between organisms.

The location and orientation of the origin of transfer of each Hfr strain are shown in Figure 1. want to use these five strains to map the locus responsible for thiamine synthesis, called thi.
