CUET PG 2021 Life Sciences Question Paper with Keys & Explanations PDF Download | helpBIOTECH Academy
helpBIOTECH Academy in Hyderabad provides comprehensive resources for CUET PG success! The CUET PG 2021 Life Sciences exam (code SCQP17), a precursor or memory-based version to the official CUET PG (started 2022), assessed candidates for M.Sc. programs in Life Sciences, Biotechnology, Botany, Zoology, Microbiology, and allied fields. It helped thousands prepare for admissions at central universities, with a focus on foundational knowledge.
Pattern: 75 MCQs (integrated syllabus), +4 for correct, -1 for wrong, 0 for unattempted. Total: 300 marks, 120 minutes. Questions emphasized conceptual and application-based topics from Biochemistry, Cell Biology, Genetics, Molecular Biology, Microbiology, Plant/Animal Sciences, and Techniques.
Here's the detailed analysis of topic-wise questions and marks from the actual CUET PG 2021 Life Sciences paper. This breakdown covers core units like Biochemistry (e.g., bioenergetics, enzymes), Techniques (e.g., spectroscopy, chromatography), and Microbiology (e.g., bioremediation, growth). High-weightage units include Biochemistry, Techniques, Microbiology, and Molecular Genetics — focus on these for upcoming exams like CUET PG 2026!
CUET PG 2021 Life Sciences - Unit-Wise Question & Marks Distribution (Based on Your Data)
From helpBIOTECH's analysis, the 2021 paper was moderate, with strong focus on foundational concepts (e.g., electronic transitions, resolving power, sedimentation). Biochemistry was overwhelmingly high-weightage, making it scoring for prepared students. Good attempts: 55-65 questions for 220+ marks.
| S.No | Unit / Topic | Questions (Approx.) | Marks (Total) | Difficulty (Estimated) |
|---|---|---|---|---|
| 1 | Techniques (Spectroscopy, Microscopy, Chromatography, Electrophoresis) | 12 | 48 | Moderate |
| 2 | Chromatin (Structure, Organization, Histones) | 5 | 20 | Moderate-Difficult |
| 3 | Biochemistry (Bioenergetics, Enzymes, Metabolism, Biomolecules) | 30 | 120 | Easy-Moderate |
| 4 | Biotech (Recombinant DNA, Tissue Culture, Applications) | 4 | 16 | Moderate |
| 5 | Microbiology (Microbes, Growth, Bioremediation, Diseases) | 6 | 24 | Moderate |
| 6 | Molecular Genetics (Transcription, Translation, Regulation, Genetics) | 5 | 20 | Moderate-Difficult |
| 7 | Plant Sciences (Physiology, Ecology, Embryology, Anatomy) | 1 | 4 | Moderate |
| 8 | Animal Sciences (Immunology, Physiology, Development, Vaccines) | 2 | 8 | Moderate |
Key Insights from CUET PG 2021 Life Sciences Paper:
- Overall Difficulty: Moderate (easy Questions on basics like transitions, resolving power; difficult on applications like DEAE cellulose, half-cell potential).
- High-Weightage: Biochemistry (120 marks) on bioenergetics/enzymes, Techniques (48 marks) on spectroscopy/chromatography—over 55% of the paper, making it biochemistry-dominant.
- Cutoff (2021 Estimates): General ~160-180 marks, OBC ~140-160, SC/ST ~100-120 (pre-official CUET; based on similar exams like JNU CEEB).
- Tip: For CUET PG 2026, prioritize biochemistry/techniques with Lehninger and lab manuals. Practice 2021-2025 papers for sequences and matching.
