Review Questions

• How does biotechnology enhance agricultural practices, and what are some examples of its applications?
  • Biotechnology enhances agricultural practices by developing genetically modified crops that can withstand pests, diseases, and environmental stresses. For example, Bt corn is engineered to produce a natural insecticide that protects against certain pests, reducing the need for chemical pesticides. This not only increases crop yields but also promotes sustainable farming practices by minimizing environmental impact.
• Discuss the role of biotechnology in healthcare and how it contributes to advancements in personalized medicine.
  • In healthcare, biotechnology plays a crucial role in developing drugs and therapies tailored to individual patients' genetic profiles. This approach, known as personalized medicine, allows for more effective treatments with fewer side effects. For instance, biopharmaceuticals produced through biotechnology include monoclonal antibodies that specifically target cancer cells, improving treatment efficacy for patients with specific types of cancer.
• Evaluate the ethical implications of biotechnology in terms of environmental impact and food safety.
  • The ethical implications of biotechnology are complex and multifaceted. On one hand, biotechnological advancements can lead to environmental benefits through sustainable practices like bioremediation. On the other hand, concerns over GMOs raise questions about biodiversity loss and food safety. Debates center around potential long-term effects on ecosystems and human health, highlighting the need for careful regulation and transparent practices in the biotechnology industry.
