Biotechnology and its Applications — Predicted 2026
AI-Predicted Question Angles for UPSC 2026
Detailed mechanism of RNAi in pest resistance.
highRNAi is a complex yet elegant mechanism. NEET often tests detailed biological processes. Questions could focus on the role of dsRNA, the specific target (nematodes), and the outcome (gene silencing leading to pest death). Students might be asked to identify the correct sequence of events or the specific molecules involved. Given its novelty and precision, it's a prime candidate for conceptual questions beyond simple recall.
Ethical implications and regulatory framework (GEAC, Biopiracy).
mediumAs biotechnology advances, ethical considerations and regulatory oversight become increasingly important. Questions on GEAC's role, the concept of biopiracy, and the need for ethical guidelines are likely. These questions test a student's broader understanding of the societal impact of science, which is a growing trend in competitive exams. Specific examples of biopiracy (like Basmati rice) are important to remember.
Comparative analysis of different molecular diagnostic techniques.
highThe chapter introduces PCR, ELISA, and recombinant DNA technology for diagnosis. Questions could involve differentiating their principles, specific applications, and advantages. For example, 'Which technique is best for early detection of HIV?' or 'What is the fundamental difference between PCR and ELISA?' This tests a deeper understanding of the tools rather than just knowing their names.
Specific applications and products of transgenic animals.
mediumBeyond 'Rosie' the cow, questions could delve into the broader uses of transgenic animals – as disease models (e.g., for cancer, cystic fibrosis), for vaccine safety testing, or chemical safety testing. Understanding the *purpose* behind creating these animals, rather than just memorizing 'Rosie', would be key. This tests the application-oriented aspect of the topic.
