Question
Chapter 19, Problem 2COQ
Summary Introduction
To determine: The similarity and differences in bacterial conjugation and eukaryotic reproduction.
Introduction: The exchange of F plasmid takes place from the F+, which is a donor, to the F- that acts as the recipient. The F factor is transferred by the process called conjugation. The F plasmid has genes that are required for conjugation as well as for certain additional properties to the bacteria.

explain why bacterial conjugation should not be considered sexual reproduction
Complete the following statement about conjugation.
Bacterial confirmation is the equivalent of sexual reproduction in eukaryotes in that it necessitates cell to cell contact. The donor cell just contain a 1. Blank which is distinct from the larger bacterial chromosome. The 2. Blank carry genes in the 3. Blank which regular the conjugation process
Briefly explain the process of bacterial conjugation, and explain how it is different from conjugation in humans.

- Why is it favorable for protozoa to replicate with schizogony versus using simple mitosis? what are the different scenarios that can occur with regards to bacterial growth within a thioglycolate tube? Explain why certain bacteria require one classification versus a different classification. A botanist has been using betaproteobacteria to grow his herb garden, because betaproteobacteria require little nutrients to grow. His garden does not grow successfully, so he comes to you for help to develop the herb garden. Which class of gram negative bacteria would you suggest and why? Why was the botanist’s original idea not going to work?arrow_forwardReview the Process Diagram, Figure 8.9, and answer this question.The type of horizontal gene transfer that involves a physical connection between two bacterial cells is transduction. expression. conjugation. transformation. recombination.arrow_forwardThe figure below shows a partial chromosome map of an E. coli Hfr strain. Each mark = 10 minutes between conjugation transfer time. If transfer of genes begins at “*” relative to the origin of transfer, what is one of the predicted results from this map? It would take less than 30 minutes to transfer all of the genes that are shown. gal and azi will rarely be transferred together. gal and ton will rarely be transferred together. Ten minutes after transfer of ton, lac will be transferred. This strain will produce very few gal recombinants.arrow_forward
- 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.arrow_forwardHow might conjugation enhance the survival of bacteria?arrow_forwardWhy does conjugation occur in bacteria?arrow_forward
