Alignment Notes:

  • Syllabus Coverage: Questions comprehensively cover DNA structure, replication, transcription, genetic code, translation, regulation (lac operon), human genome project, DNA packaging, and mutations as per NCERT Class 12 Biology Chapter 6.
  • Question Types: Includes factual recall (e.g., discoverers, enzymes, structures), conceptual understanding (e.g., Chargaff’s rule, central dogma, operon regulation, genetic code properties), and application-based reasoning (e.g., mutation consequences, interpreting experiments like Meselson-Stahl/Hershey-Chase, HGP findings).
  • Language & Level: Uses clear, precise language appropriate for Class 12 CBSE students. Avoids unnecessary jargon beyond the NCERT scope.
  • CBSE Pattern: Follows the standard MCQ format (4 options, single correct answer) prevalent in CBSE board exams. Distractors are plausible misconceptions.
  • NCERT Basis: All concepts, definitions, experiments, and facts are drawn directly from the NCERT Class 12 Biology textbook.
