GAT-B 2024 Question Paper with Answers PDF Download | helpBIOTECH Academy
Welcome to helpBIOTECH Academy's dedicated page for the GAT-B 2024 exam! The Graduate Aptitude Test - Biotechnology (GAT-B) 2024, conducted by the National Testing Agency (NTA) on behalf of the Department of Biotechnology (DBT), was held on April 20, 2024. This computer-based test (CBT) lasted 3 hours (180 minutes) and aimed to select candidates for M.Sc. Biotechnology and allied programs in participating institutions across India. Over 10,000+ students appeared, with results declared in May 2024.
The exam pattern included two sections: Section A (60 compulsory MCQs at 10+2 level, 1 mark each, covering Physics, Chemistry, Maths, Biology, and General Aptitude) and Section B (100 MCQs at graduate level in Biotechnology, but attempt only 60, 3 marks each). Negative marking: -0.5 for Section A wrong answers, -1 for Section B. Total marks: 240 (60 from A + 180 from B).
Here's the detailed analysis of topic-wise questions and marks from the actual GAT-B 2024 Biotechnology paper (conducted on April 20, 2024). This breakdown covers Section A (10+2 level basics, 1 mark each) and Section B (graduate-level biotech concepts, mostly 3 marks each). High-weightage units include Biochemistry, Molecular Biology, Genetics, Immunology, and Recombinant DNA Technology — focus on these for upcoming exams like GAT-B 2026!
GAT-B 2024 - Unit-Wise Question & Marks Distribution (Based on Memory & Coaching Analysis)
From student feedback and expert reviews, GAT-B 2024 was moderate overall. Section A was easy-moderate (focusing on conceptual basics), while Section B was moderate-difficult (analytical questions in biotech). High scorers targeted core topics like Proteins, Genetics, and rDNA.
| S.No | Unit / Topic | Section A Questions (1 mark each) | Section B Questions (3 marks each, attempted 60/100) | Total Marks (Approx.) |
|---|---|---|---|---|
| 1 | Physics (Mechanics, Optics, etc.) | 15-20 | 0 | 15-20 |
| 2 | Chemistry (Organics, Inorganics) | 15-20 | 0 | 15-20 |
| 3 | Mathematics/Quantitative Aptitude | 10-15 | 0 | 10-15 |
| 4 | Biology Basics (10+2 Level) | 10-15 | 0 | 10-15 |
| 5 | Biochemistry (Amino Acids, Proteins, Enzymes) | 0 | 8-12 | 24-36 |
| 6 | Molecular Biology (DNA, RNA, Replication) | 0 | 10-15 | 30-45 |
| 7 | Genetics & Evolution | 0 | 8-10 | 24-30 |
| 8 | Immunology | 0 | 6-8 | 18-24 |
| 9 | Recombinant DNA Technology (rDNA, Techniques) | 0 | 8-12 | 24-36 |
| 10 | Cell Biology & Physiology | 0 | 6-10 | 18-30 |
| 11 | Microbiology & Virology | 0 | 5-8 | 15-24 |
| 12 | Plant & Animal Biotechnology | 0 | 4-6 | 12-18 |
| 13 | Bioinformatics & Biostatistics | 0 | 3-5 | 9-15 |
Key Insights from GAT-B 2024 Paper:
- Overall Difficulty: Moderate (Section A: Easy-Moderate; Section B: Moderate-Difficult). Questions tested conceptual understanding and application.
- High-Weightage in Section B: Molecular Biology and Biochemistry (30-45 marks) — many analytical questions on enzymes, DNA replication, and protein structure.
- Surprises: More emphasis on rDNA techniques and immunology than previous years; fewer on bioinformatics.
- Preparation Tip: Master graduate-level biotech syllabus (as per DBT guidelines). Practice previous papers like this 2024 one for time management — aim for 100+ marks for top ranks.
