Expected Weightage
The Common University Entrance Test (CUET) for Biotechnology and its Applications has a specific marking pattern and chapter-wise weightage that can be analyzed based on past trends (2022-2024). Below is a detailed breakdown:
1. CUET Biotechnology Marking Pattern (Last 3 Years)
- Total Questions: 50 (out of which 40 must be attempted)
- Marks per Correct Answer: +5
- Marks per Incorrect Answer: -1
- Unattempted Questions: 0
- Maximum Marks: 200 (40 × 5)
2. Chapter-wise Weightage (Approximate Trends)
The syllabus is based on NCERT Class 12 Biology (Unit 10: Biotechnology Its Applications). The weightage varies slightly each year, but the following pattern is observed:
| Chapter/Topic | Weightage (2022-2024) | Expected No. of Questions |
|---|---|---|
| Principles of Biotechnology (Tools, PCR, Vectors, etc.) | 25-30% | 8-10 |
| Genetic Engineering (Recombinant DNA Technology) | 20-25% | 7-9 |
| Biotechnological Applications in Agriculture (GM Crops, Bt Cotton, RNAi, etc.) | 15-20% | 5-7 |
| Biotechnological Applications in Medicine (Gene Therapy, Vaccines, Insulin, etc.) | 15-20% | 5-7 |
| Transgenic Animals, Ethical Issues, and Biosafety | 10-15% | 3-5 |
| Other Topics (Bioinformatics, IPR, Biopatents, etc.) | 5-10% | 2-4 |
3. Key Observations (2022-2024)
-
Most Important Chapters:
-
Recombinant DNA Technology (highest weightage)
-
PCR Gene Cloning (frequently asked)
-
GM Crops Bt Toxin (application-based questions)
-
Gene Therapy Insulin Production (medical applications)
-
Least Important Chapters:
-
Ethical Issues Biosafety (fewer questions)
-
Bioinformatics Biopatents (occasionally asked)
-
Question Types:
-
Conceptual (60%) – Definitions, steps in PCR, gene cloning
-
Application-based (30%) – GM crops, gene therapy
-
Diagram-based (10%) – Gel electrophoresis, PCR steps
4. Preparation Strategy
-
Focus Areas:
-
Recombinant DNA Technology (20-25 marks)
-
PCR Cloning Vectors (15-20 marks)
-
Bt Cotton RNAi (10-15 marks)
-
Insulin Production Gene Therapy (10-15 marks)
-
Avoid Neglecting:
-
Transgenic Animals Ethical Issues (5-10 marks)
-
Biopatents Bioinformatics (2-4 marks)
5. Expected Changes (2025 Beyond)
- More Application-based Questions (especially in medicine agriculture)
- Increased Focus on Ethical Biosafety Concerns (due to recent biotech advancements)
Conclusion
For CUET Biotechnology , prioritize Recombinant DNA Technology, PCR, GM Crops, and Medical Applications. Solve previous years’ papers (2022-2024) to identify repeated patterns.
