Summary Introduction
Introduction:
Transduction is the process by which foreign DNA (deoxyribonucleic acid) is introduced into a recipient bacterial cell by means of a virus or infecting phage (bacteriophage) or viral vector. The DNA containing the capacity of a phage is limited and only a small amount of donor’s DNA can be transferred to the recipient.

- Which of the following is NOT a method by which bacteria can be resistant to antibiotics? Select one: a. Utilise an alternate pathway of gene expression that is not targeted by the antibiotic. b. Alter the binding site of the antibiotic, to either prevent it binding, or remove it from the site. c. Production of enzymes that bind to and break down the specific antibiotic. d. Production of a cell membrane pump that translocates antibiotics outside the cell. A potential side effect of antibiotic use is a secondary bacterial or fungal infection, usually associated with regions like the skin, upper-respiratory tract or genitalia. What is the most likely reason for the formation of these secondary infections? Select one: a. Antibiotics do not work on viruses, so they are able to establish infections in these locations. b. Organisms that are antibiotic resistant are usually more virulent, meaning they can survive and cause infection. c. The antibiotic kills off normal flora, providing an…arrow_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_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? (photo linked) 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_forward
- Bacteria exposed to viruses incorporate sections of the virus’s DNA into the CRISPR array sequences in their genome. This mechanism allows bacteria to fight off the viruses, like an immune response: the information in CRISPR spacers served as “coordinates” for recognizing and cutting up invading DNA sequences. Describe what might happen under the conditions described after a bacteriophage infects a bacterial cell and releases its DNA into the bacterial cell. Explain why: 1. The invading phage DNA is recognized by the Cas proteins but not inserted into the CRISPR array region of the bacterial genome: The bacteria will be unable to elicit an immune response and will succumb to the phase infection 2. The cas genes on the bacterial genome contains a missense mutation that increases its cleavage/cut activityThe bacteria will elicit an immune response that will successfully fight the phage infectionarrow_forwardA positive-strand RNA virus: a.must first be converted to a mRNA before viralproteins can be translated b.is not recognized by host ribosomes. c.can directly translate viral proteins. d.will be degraded by host enzymes. e.needs RNA dependent RNA polymerase to get converted into mRNAarrow_forwardWhich statement(s) indicates one or more benefits of electroporation?
