Questions and Answers

What is a potential concern related to the use of genetically modified bacteria in producing human insulin?

  • There is a risk of antibiotic resistance genes transferring to harmful bacteria. (correct)
  • The bacteria may produce insulin that causes allergic reactions in humans.
  • The human genes carried by the bacteria may interfere with the insulin production process.
  • The bacteria could produce insulin with reduced effectiveness.

    • What is one of the health concerns associated with consuming genetically modified organisms (GMOs)?

  • Lower nutrient content in GM foods.
  • Higher susceptibility to viral infections.
