- Imagine you go to the doctor because you are sick. You get antibiotics, but you hurry out of the hospital as fast as you can so you don’t pick up any antibiotic resistance genes as well. If genes were transferred directly from the environment, you could pick up a resistance gene by breathing the air. What type of gene transfer allows cells to pick up genes directly from the environment? a. Transformation b. Transduction c. Conjugation d. All of the abovearrow_forwardCompare the three mechanisms of gene transfer in bacteria: transformation, conjugation, and transduction.arrow_forwardPart A: Antibiotic resistance is a major health concern. Resistance to various antibiotics can be transferred by a. all options. b. transduction. c. conjugation. d. transformation. Part B: Movement of genetic information through transduction requires that a. free DNA is available in the environment. b. physical contact occurs between cells. c. transposable elements occur in a chromosome. d. viruses have infected a cell.arrow_forward

- Which of the following statements correctly describes a process by which bacteria become resistant to antibiotics? A. bacteria reproduce slowly, allowing mutation to become widespread in a population. B. some bacteria produce exotoxins that breakdown antibiotics, rendering them nonfunctional C. conjugation spreads antibiotic resistance genes rapidly in a population D. antibiotics cause mutation in bacteria, making them resistant.arrow_forwardIn 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.arrow_forwardDescribe the 3 ways in which bacteria can transfer genetic material to each other via horizontal gene transfer. Be sure to explain the following: How is DNA transferred between bacteria, is there direct contact between bacteria and whether a plasmid is involved or not.arrow_forward
