- Engineered bacteria are commonly used and cultured in pharmaceutical laboratories to produced drugs like insulin. However, during one instance, with the desire to increase the rate of insulin production, one scientist tried to modify the process and put another substance (chemical x) in the growth medium which is chemically almost the same to the substance (chemical x’) normally put in the medium. After which, the scientist found out that the amount of insulin produced in the medium decreases as compared to the normal production. Again, within the context of our discussion, explain the possible reason for the observed result.arrow_forwardCompare and contrast the advantages and disadvantages of selective breeding versus genetic modification. Why might a person choose to use selective breeding over genetic modification? Why might a person choose to create a GMO over a selectively bred organism? Use three to five sentences to formulate your argument.arrow_forwardBacterial species that are harmful, as well as others that are beneficial, are found living in the human body. To slow the rate of developing antibiotic resistance in bacteria, physicians are being encouraged to use "narrow-spectrum" antibiotics- those that target only a few bacterial types. How can the information learned by antibiotic sensitivity testing be used by physicians who must choose antibiotics that inhibit the growth of bacteria causing disease but that do not interfere with beneficial bacteria?arrow_forward
- What is the role of Agrobacterium tumefaciens in the production of transgenic plants?a. Genes from A. tumefaciens are inserted into plant DNA to give the plant different traits.b. Transgenic plants have been given resistance to the pest A. tumefaciens.c. A. tumefaciens is used as a vector to move genes into plant cells.d. Plant genes are incorporated into the genome of Agrobacterium tumefaciensarrow_forwardAntibiotics are widely used in raising livestock in the US. Visit the websites below for the general public and learn a little more about this practice. Denmark has chosen to significantly restrict the use of antibiotics in livestock and can be seen as a potential model for viewing that impact on livestock industry, but Denmark is a small country with different economic constructs than in the US. Although there is controversy about the impact that this practice has in the development of antibiotic resistance of significance to the human population, it is enough to raise concerns and promote discussion about what, if any, action should be taken in the US. POST your response to the following questions, along with a rationale that includes some evidence to support your opinion (reference where your information comes from). 1) After looking at some of the arguments on both sides, do you think a US ban is warranted? 2) Would you be willing to pay more for your food as a result? 3)Is…arrow_forward1.1 Give an overview of the positive and negative effects of microbial biotechnology in agriculture. 1.2 Give a detailed explanation of how recombinant DNA technology can be used for the management and control of emerging diseases.

- Genetically modified organisms (GMOs) are used to create human growth hormone, insulin and clotting factor proteins that are used to treat dwarfism, diabetes and hemophilia respectively. Several crops such as corn and soybean have also been genetically modified in order to facilitate either the management or growth of these crops. Why do you think there is push back or opposition against the use of GM food crops but not in the use of products such as insulin, which is also created using GMOs?arrow_forwardWhat are secondary metabolites? In terms of biotechnology, how do we get bacteria to produce them with cloning technology? Explain the stages in schematics and explanations.arrow_forwardResults from a Kirby Bauer antibiotic assay on a Gram-negative bacterial culture are described as follows: A) the bacterium is resistant to penicillin, an antibiotic that targets synthesis of the peptidoglycan cell wall and B) the bacterium is resistant to tetracycline, an antibiotic that targets the small subunit of the ribosome, inhibiting protein synthesis. Which of the results represents intrinsic resistant and which represents acquired resistants?arrow_forward
- In Experiment I, you established that beneficial mutations are rare. In Experiment II, you showed that the environment does not affect the probability of a beneficial mutation occurring. Knowing this, why then are mutations responsible for antibiotic resistance in bacteria so common?arrow_forwardVarious strains of bacteria are able to transfer genes to eukaryotic hosts. This process of horizontal gene transfer often results in the formation of enzymes in the host organism that assist in metabolic pathways. Which of the following is the most likely explanation for why bacterial genes are able to successfully transfer genes that produce enzymes in eukaryotic cells? A - Bacteria and Eukarya have similar mechanisms for the formation and use of enzymes in metabolic processes. B - Bacteria and Eukarya use the same enzymes in all of their metabolic processes so the genes are interchangeable. C - Bacteria and Eukarya share similar reproductive mechanisms so the cells reproduce without recognizing foreign DNA. D - Bacteria and Eukarya have the same mechanism for replicating DNA so genes can easily be transferred between the two types of cells.arrow_forwardIf you were developing a new “broad-spectrum” antibiotic to kill a widevariety of bacteria, which cell structures and pathways would you target?Which of those targets also occur in eukaryotic cells, and why is thatimportant? How would your strategy change if you were designing a new“narrow-spectrum” antibiotic active against only a few types of bacteria?arrow_forward
