2. Expanded Modules for Biotechnology Students:
- System Physiology: Advanced plant and animal physiological responses, neurobiology, and endocrine mechanisms.
- Ecology & Evolutionary Biology: Population ecology, community dynamics, macroevolution, and molecular phylogenetics.
- Bioinformatics & OMICS: Structural bio-modeling, biological database algorithms, sequence alignment strategies, and structural genomics.
Eligibility Criteria & Age Limits
- Educational Qualification: M.Sc. or equivalent degree, B.S. (4-year duration), B.E./B.Tech, B.Pharm, MBBS, or Integrated BS-MS/M.Sc. in Life Sciences, Biotechnology, Biochemistry, Microbiology, or related biological streams.
- Minimum Marks: Minimum 55% aggregate marks for General/General-EWS/OBC-NCL candidates, and 50% aggregate marks for SC/ST/Third Gender/PwD candidates.
- Result Awaited (RA) Category: Final-year Master’s degree students or bachelor degree holders awaiting final results are eligible to apply provisionally.
- Age Limit (as of December 1, 2026):

- Assistant Professorship / Ph.D. Admission: No upper age limit.
Fellowship Structure & Monthly Stipends
While the examination is unified, funding agencies will disburse monthly stipends through their respective administrative channels:
- CSIR JRF Scheme:
- JRF Stipend (Years 1–2): ₹37,000 per month + applicable HRA.
- SRF Stipend (Years 3–5): ₹42,000 per month + applicable HRA (upon satisfactory progress assessment).
- Annual Contingency: ₹20,000 per annum.
- DBT Fellowship Scheme:
- Candidates merit-listed under the Department of Biotechnology quota will receive equivalent stipend funds directly transferred via DBT’s institutional fellowship portal.
Category-Wise Application Fees

Frequently Asked Questions (FAQs)
1. Why have CSIR NET Life Sciences and DBT-BET been merged?
The National Testing Agency (NTA) merged the two examinations to create a unified single-window evaluation system for life sciences and biotechnology aspirants. This eliminates duplicate exams, reduces administrative costs, and streamlines candidate evaluation for research fellowships and assistant professorships across India.
2. Do I need to fill separate application forms for CSIR JRF and DBT Fellowship?
No. Candidates only need to register once for the Life Sciences & Biotechnology (LS & BT) paper on the official NTA portal (csirnet.nta.nic.in). Candidates can select their preferences for JRF, Assistant Professorship, or both during the online submission process.
3. Has the syllabus changed after the merger?
Yes. The unified syllabus integrates classical biological sciences (such as cell biology, genetics, ecology, and plant/animal physiology) with core biotechnology subjects, including Bioprocess Engineering, Recombinant DNA Technology, Bioinformatics, and Applied Immunology.
4. How will the fellowships be funded and disbursed?
While the examination and merit list generation are handled by NTA, the funding mechanisms remain separate:
- CSIR JRF: Awarded and funded directly by the Council of Scientific and Industrial Research.
- DBT Fellowship: Awarded and funded directly by the Department of Biotechnology (DBT) to candidates qualifying under the biotechnology merit criteria.
5. What is the examination pattern for the merged paper?
The exam is a 3-hour Computer-Based Test (CBT) consisting of 145 Multiple Choice Questions (MCQs) for a total of 200 marks. Candidates must attempt 75 questions across three parts:
- Part A: 15 out of 20 questions (General Aptitude – 30 Marks)
- Part B: 35 out of 50 questions (Core Subject – 70 Marks)
- Part C: 25 out of 75 questions (Analytical/Applied – 100 Marks)
6. Can final-year Master’s degree students apply?
Yes. Students currently pursuing their Master’s degree or awaiting their final results are eligible to apply under the “Result Awaited” (RA) category.
Conclusion
The structural merger of DBT-BET into the CSIR-UGC NET December 2026 examination as Life Sciences & Biotechnology (LS & BT) marks a major reform in Indian higher education and research recruitment. By unifying exam administration while preserving distinct funding avenues from CSIR and DBT, the NTA has simplified the career pathway for thousands of research aspirants.
Aspirants are strongly recommended to review the updated hybrid syllabus, adjust their preparation strategy to cover both theoretical and applied modules, and complete their online applications at csirnet.nta.nic.in before the deadline on November 5, 2026.
