The NEET exam typically takes place in the first half of the year, usually between the months of May and June. However, please note that exam dates can be subject to change, so it’s important to stay updated with the official announcements made by the NTA.
To ensure you are well-prepared for the biotechnology and its applications topic, it is recommended to allocate sufficient time for studying and revising the relevant concepts and subtopics within the NEET biology syllabus. This will help you build a strong foundation and perform well in the exam.
Case Study on NEET BIOLOGY SYLLABUS Biotechnology and its applications
Application of Biotechnology in Agriculture
Introduction: Biotechnology has revolutionized various sectors, and agriculture is one of the areas that has significantly benefited from biotechnological advancements. In this case study, we will explore the application of biotechnology in agriculture, focusing on the genetic engineering of crops and the controversy surrounding genetically modified organisms (GMOs).
Background: With a growing global population and increasing food demand, there is a need to develop sustainable and high-yielding crop varieties. Biotechnology offers valuable tools and techniques to enhance crop productivity, nutritional value, and resistance to pests, diseases, and environmental stressors.
Case Study Scenario: Farmers in a developing country are facing challenges with their crop yield due to frequent pest attacks, particularly by a destructive insect that causes substantial damage to their staple crop. Traditional methods of pest control, such as chemical pesticides, are costly and have limited effectiveness. The government and agricultural experts are exploring biotechnological solutions to address this issue.
Biotechnological Approach: The scientists propose the genetic engineering of the crop to introduce a gene from a naturally occurring bacterium that produces a protein toxic to the pest insect. This protein, known as Bacillus thuringiensis (Bt) toxin, selectively kills the target insect while being harmless to humans and beneficial organisms like bees and butterflies.
Implementation and Benefits: The scientists develop a genetically modified crop variety by incorporating the Bt toxin gene into the crop’s genome. This genetically modified crop is resistant to the pest and offers several advantages:
- Enhanced Pest Resistance: The Bt toxin gene provides built-in resistance against the target pest, reducing crop damage and yield losses.
- Reduced Pesticide Use: As the crop produces its own insecticide, farmers can reduce the application of chemical pesticides, leading to cost savings and minimizing environmental pollution.
- Improved Crop Yield and Quality: By reducing pest damage, the crop yield and quality improve, ensuring better incomes for farmers and a more reliable food supply.
Controversy and Ethical Considerations: Despite the potential benefits, the introduction of genetically modified crops and GMOs is not without controversy. Opponents of GMOs raise concerns about potential environmental risks, effects on human health, and the control of seed supply by large corporations. Some argue for more extensive long-term studies and transparent labeling of genetically modified products to allow consumers to make informed choices.
Conclusion: The application of biotechnology in agriculture, specifically genetic engineering of crops, offers promising solutions to address various agricultural challenges. The use of genetically modified crops can enhance pest resistance, reduce pesticide usage, and improve crop yield and quality. However, it is essential to consider ethical and environmental implications, conduct thorough safety assessments, and promote transparent labeling to ensure the responsible and sustainable use of biotechnology in agriculture.
Note: This case study provides a hypothetical scenario to illustrate the application of biotechnology in agriculture. The specifics of each case study may vary depending on the context and real-world scenarios.
