Based on 53 questions across 22 years, UPSC has consistently tested aspirants' understanding of Biotechnology & Genetics within the broader Science & Technology syllabus. The questions range from factual recall to application-based analysis.
Recent trends show UPSC moving towards statement-based questions that combine multiple aspects of Biotechnology & Genetics. Aspirants should focus on understanding concepts rather than memorizing isolated facts.
