- . When a virus mistakenly picks up a segment of host bacterial DNA, packages it into a viral particle, then transfers it to a new bacterial host cell, this transfer of DNA is properly called: transduction transformation conjugation transversion transitionarrow_forwardA transducing particle injects all of the DNA that it contains into a bacterial cell. Which of the following are TRUE? A. The bacterium becomes Hfr B. The bacterium becomes F+ C. The bacterium immediately acquires new functions as the injected DNA is rapidly transcribed and translated into mRNA and proteins D. This injected DNA can integrate into the bacterium’s genome through a process called recombinationarrow_forwardAn extra chromosomal segment of circular DNA of a bacterium is used to carry gene of interest into the host cell.

- 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)…arrow_forwardBriefly discuss the following questions in 3 to 5 sentences.
