Which of the following is an example of horizontal gene transfer? a. the transmission of an eye color gene from father to daughter b. the transmission of a mutant gene causing cystic fibrosis from father to daughter c. the transmission of a gene conferring pathogenicity (the ability to cause disease) from one bacterial species to another d. the transmission of a gene conferring antibiotic resistance from a mother cell to its two daughter cells e. all of the above
You mix two auxotrophic strains of bacteria; one is leu+ trp+ his– met– and the other is leu– trp– his+ met+. After mixing the two strains, you plate the bacteria on minimal medium and observe a few prototrophic colonies (leu+ trp+ his+ met+). To determine whether gene transfer has occurred through conjugation, transformation, or transduction, you design an experiment in which you place filters between the two strains to see if gene transfer occurs. You set up three treatments:-Treatment A No filter, allowing contact between the bacterial strains-Treatment B Filter that blocks cells, but allows viruses and DNA through the filter-Treatment C Filter that blocks cells and viruses, but allows DNA through the filter When you check the results of your experiment, you find prototrophic colonies have occurred following treatments A and B, but not following treatment C. You conclude that gene transfer occurred through... Answer Choices Available: A) Conjugation B) Transformation C)…
Which of the following bacterium is used for gene transfer in plants?a) Agrobacteriumb) Azatobacterc) Rhizobiumd) Ecoli
When an E. coli donor cell duplicates a strand of plasmid DNA, and passes this DNA strand to a recipient E. coli cell, without the use of naked DNA in solution or of a viral vector, this is: an example of horizontal gene transfer by means of lysogenic bacteriophages an example of horizontal gene transfer by means of lytic bacteriophages an example of horizontal gene transfer by means of transformation an example of horizontal gene transfer by means of transduction an example of horizontal gene transfer by means of conjugation
A group of genetics students mix two auxotrophic strains of bacteria: one is leu+ trp+ his− met− and the other is leu− trp− his+ met+. After mixing the two strains, they plate the bacteria on minimal medium and observe a few prototrophic colonies (leu+ trp+ his+ met+). They assume that some gene transfer has taken place between the two strains. How can they determine whether the transfer of genes is due to conjugation, transduction, or transformation?
In Hershey and Chase’s experiment investigating which biological molecule carries genetic information, they found that phage DNA with radiolabeled phosphorus was retained in bacterial cells after transduction. To conclude that DNA is the genetic material, what assumption did they have to make? A. Protein does not enter the bacterium during transduction. B. DNA does not stay in the media after transduction. C. All of the phage DNA was radiolabeled. D. Bacteria can be transduced by phage.
Part A: Which of the following is not a reason that microbes benefit from horizontal gene transfer? cells can acquire useful traits quickly. all new types of DNA are good. genetic diversity is ehanced. All examples are reasons that microbes benefit. Part B:Transposable elements can do all of the following except move from one position to another in a chromosome. cause disruption in genes in which they insert. move from one cell to another. copy themselves, and the copy can insert somewhere else.
What is horizontal gene transfer and how can this process potentially change how we view relatedness among the three Domains? Provide an example of a species with characteristics that results from horizontal gene transfer.
find an example of a set of genes that have been horizontally gene transferred between bacteria or archaea. Which organisms are the genes transferred between? Explain the set of genes that were transferred. Include what they are for and what the advantage to sharing those genes are.What do the organisms use the genes for?Which organisms the transfer happened between?What might be the advantage be to share the genes with other organisms?
When a bacteriophage accidentally incorporates a fragment of host DNA in its capsid and delivers it to another (living) bacterial cell, the process is called _____. transformation transduction conjugation speciation
The Kishony performed a simple but elegant experiment using a “mega-plate.” Which of the following is a fair conclusion that can be drawn from this study? The majority of antibiotic resistance occurs via horizontal gene transfer (HGT) between Actinobacteria Sensitive bacteria may acquire resistance to high concentrations of the antibiotic through many mutations Bacteria will gradually lose resistance to an antibiotic if you plate them on a large enough plate Bacteria will migrate via chemotaxis away from recombinant phage used in phage therapy
Some strains of Escherichia coli bacteria have acquired the ability to produce the harmful Shiga toxin, normally produced by Shigella dysenteriae. Which statements best explain why this occurs? Mark all that apply. A. conjugation between two different species of bacteria allowed both strains of bacteria to express a virulence factor B. transformation resulted in expression of a virulence factor C. horizontal gene transfer between different species of bacteria D. transduction of a specific gene resulted in expression of new traits
