CUET PG 2023 Life Sciences Question Paper with Keys & Explanations PDF Download | helpBIOTECH Academy
helpBIOTECH Academy in Hyderabad offers premium resources for CUET PG aspirants! The CUET PG 2023 Life Sciences exam (code SCQP17), held by NTA from June 5 to 17, 2023, evaluated candidates for M.Sc. programs in Life Sciences, Biotechnology, Botany, Zoology, Microbiology, and allied areas across 100+ universities. Over 80,000 students participated, with results in July 2023.
Pattern: 75 MCQs (integrated syllabus), +4 for correct, -1 for wrong, 0 for unattempted. Total: 300 marks, 120 minutes. Questions covered 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 2023 Life Sciences paper (conducted June 5-17, 2023). This breakdown covers core units like Techniques (e.g., spectroscopy, PCR, chromatography), Biochemistry (e.g., enzymes, metabolism), and Animal Sciences (e.g., immunology, physiology). High-weightage units include Techniques, Biochemistry, Plant Sciences, and Animal Sciences — focus on these for upcoming exams like CUET PG 2026!
CUET PG 2023 Life Sciences - Unit-Wise Question & Marks Distribution (Based on Your Analysis)
As per helpBIOTECH's expert breakdown, the 2023 paper was moderate, with balanced units but conceptual focus (e.g., annealing temps, anaphylatoxins). High scorers attempted 60+ questions accurately for 220+ marks.
| S.No | Unit / Topic | Questions (Approx.) | Marks (Approx., +4 each) | Difficulty |
|---|---|---|---|---|
| 1 | Techniques & Methods (Principles and applications of chromatography, spectroscopy, microscopy, electrophoresis, centrifugation, blotting, PCR & radioisotope techniques) | 12 | 48 | Moderate |
| 2 | Chromatin Structure (Organization of chromosomes in prokaryotes and eukaryotes, chromatin types, centromere, Telomere and concept of gene) | 7 | 28 | Moderate-Difficult |
| 3 | Biochemistry (Structure and functions of proteins, DNA, carbohydrates, lipids & vitamins. Bioenergetics, Glycolysis, TCA cycle, Electron Transport System and ATP synthesis, oxidation and synthesis of fatty acid, membrane structure and function) | 12 | 48 | Easy-Moderate |
| 4 | Biotech (Recombinant DNA technology, principles of gene cloning, applications of biotechnology in medicine, industry and agriculture, animal & plant cell culture, environmental biotechnology) | 4 | 16 | Moderate |
| 5 | Microbiology (Diversity of microbes, bacterial reproduction, antimicrobial agents, significance of microbes in the industry and agriculture, antigen, antibody, complement systems, immunity, vaccines, plant virus, animal virus and environmental microbiology.) | 8 | 32 | Moderate |
| 6 | Molecular Genetics (Principles of inheritance, linkage & crossing over, chromosomal aberrations, extrachromosomal inheritance, replication, transcription, translation, DNA repair and population genetics) | 6 | 24 | Easy-Moderate |
| 7 | Plant Sciences (Bryophytes, Pteridophytes, Gymnosperms, Angiosperms, Vascular system in plants, Economic important of plants, Photosynthesis, Photoperiodism, Vernalization, and Biogeochemical cycle) | 12 | 48 | Moderate |
| 8 | Animal Sciences (Characteristics of invertebrates and vertebrates, anatomy and physiology of different system of humans, nerve impulse transmission, endocrinology, human diseases. Apoptosis and cancer, inherited diseases, animal cell culture) | 13 | 52 | Moderate |
Key Insights from CUET PG 2023 Life Sciences Paper:
- Overall Difficulty: Moderate (conceptual Questionss like spectroscopy wavelengths easy; applications like bioremediation, immunology tough).
- High-Weightage: Techniques, Biochemistry, Plant Sciences, and Animal Sciences (~160 marks combined) — focus on PCR/chromatography, enzymes/metabolism, physiology/ecology, immunology/physiology.
- Trends vs. Later Years: Balanced across units, unlike 2024's molecular genetics or 2025's molecular genetics and microbiology
- Cutoff (2023 Category-Wise): General ~180-200 marks, OBC ~160-180, SC/ST ~120-140, EWS ~170-190 (estimates from Careers360, PW; actual university-specific like JNU ~45-70 normalized).
- Tip: For CUET PG 2026, master high-weightage units with NCERT + advanced books (Lehninger for Biochemistry, Watson for Mol Genetics). Practice matching and sequences from 2023-2025 papers.
