Genetic Engineering — Prelims Strategy

Prelims Strategy

For Prelims, focus on factual accuracy and conceptual clarity. Master the definitions of key terms like genetic engineering, GMO, gene therapy, CRISPR-Cas9, base editing, and prime editing. Understand the core principles and the basic mechanism of CRISPR-Cas9 (guide RNA, Cas9, DNA cut, repair).

Memorize important examples of GM crops (Bt cotton, Golden Rice) and their specific traits. Know the names and functions of regulatory bodies in India (GEAC, RCGM, IBSC) and key international agreements (Cartagena Protocol).

Pay close attention to recent policy changes, such as the differentiated regulation for gene-edited crops in India. Questions often test the 'what,' 'how,' and 'who' of genetic engineering. Practice MCQs that involve matching applications with techniques or identifying correct statements about regulatory bodies.

Be aware of common misconceptions or 'trap' options, especially regarding the specific applications of different GM products or the precise functions of gene-editing tools. Vyyuha advises creating flashcards for key terms, techniques, and their primary applications.
