What aspirants read for DBT-BET Biotechnology, unit by unit, and what each title is for.
What qualifying gets you. Candidates in the top band, historically the leading two hundred and seventy-five, are placed in Category-I, which carries a DBT Junior Research Fellowship that becomes active on PhD registration and is portable to any recognised university or institute in India — the student chooses the laboratory, not the other way round. The fellowship runs for two years as JRF and three further years as Senior Research Fellow, up to five years or the date of the PhD viva-voce, whichever is earlier, with a house rent allowance and an annual contingency grant. Category-II candidates become eligible to be appointed as Junior Research Fellow on DBT-sponsored research projects at a stipend equivalent to the NET and GATE scale, and may also join a PhD through an institute's own selection process. Clearing BINC gives DBT-certified bioinformatician status and JRF eligibility for PhD work, treated at par with NET, GATE and BET, and the top ten qualifiers receive a cash incentive.
The DBT Biotechnology Eligibility Test rewards a different balance from CSIR-NET: recombinant DNA technology, process engineering and bioinformatics carry far more weight than classical biology. Glick and Primrose between them cover the cloning and genomics half, and candidates from non-engineering backgrounds usually have to build the bioprocess side from scratch with Doran, working the examples until the material balances stop being intimidating. Satyanarayana is the quick Indian survey used to fill in industrial, plant and environmental biotechnology before the exam. The Pathfinder problem book is worked in the final weeks to check retention rather than to learn anything new.
Titles are tagged core reading — the ones scholars work right through — or reference, the ones they look things up in. Editions are given where the current edition is what you want to buy.

| Unit | What it covers |
|---|---|
| Section A — General science and aptitude | Physics, chemistry, biology and mathematics at 10+2 level, together with basic quantitative and logical reasoning. This section is compulsory and is deliberately broad, so a candidate from a narrow specialisation should not skip it. |
| Biochemistry and biophysics | Structure and function of carbohydrates, lipids, proteins and nucleic acids; enzyme kinetics, mechanisms and regulation; bioenergetics and metabolic pathways including glycolysis, the citric acid cycle and oxidative phosphorylation; membrane biochemistry; and the biophysical principles behind spectroscopy, centrifugation and chromatography. |
| Cell biology and molecular biology | Cell architecture and organelle function; the cytoskeleton and cell motility; cell cycle and its regulation, apoptosis; DNA replication, repair and recombination; transcription and RNA processing; translation and post-translational modification; and the regulation of gene expression in prokaryotes and eukaryotes. |
| Genetics and genomics | Mendelian and non-Mendelian inheritance; linkage and mapping; mutation and DNA damage; population genetics; microbial genetics; human genetics and genetic disorders; structural and functional genomics; next-generation sequencing and genome assembly; and transcriptomics and proteomics. |
| Microbiology | Microbial diversity, taxonomy and classification; bacterial structure, growth and metabolism; microbial genetics and gene transfer; virology; industrial and environmental microbiology; food and agricultural microbiology; and sterilisation, antimicrobials and antibiotic resistance. |
| Immunology | Innate and adaptive immunity; antigens and antibodies and their structure and function; the major histocompatibility complex and antigen processing and presentation; T-cell and B-cell development and activation; the complement system; hypersensitivity, autoimmunity and transplantation immunology; vaccines and immunodiagnostics; and monoclonal antibody technology. |
| Recombinant DNA technology and genetic engineering | Restriction enzymes and cloning vectors including plasmids, phage, cosmid, BAC and YAC systems; construction and screening of genomic and cDNA libraries; PCR and its variants; site-directed mutagenesis; expression systems in bacterial, yeast, insect, mammalian and plant hosts; gene knockouts and genome editing; and DNA sequencing strategies. |
| Plant and animal biotechnology | Plant tissue culture, micropropagation, somatic hybridisation and haploid production; transgenic plants and their applications in crop improvement; molecular markers and marker-assisted breeding; animal cell culture and its media, growth and cryopreservation; transgenic animals and animal cloning; stem cells and regenerative medicine; and hybridoma technology. |
| Bioprocess engineering and technology | Microbial growth kinetics; bioreactor design, types and operation; sterilisation and aeration and agitation; batch, fed-batch and continuous culture; upstream and downstream processing including cell disruption, precipitation, chromatography and drying; enzyme and cell immobilisation; and process scale-up and economics. |
| Bioinformatics and computational biology | Biological databases for sequence, structure and function; sequence alignment, BLAST and multiple alignment; phylogenetic analysis; protein structure prediction, homology modelling and molecular docking; genome annotation; systems biology and network analysis; and programming and scripting for biological data — the last of these is the core of the BINC practical stage. |
| Analytical techniques and instrumentation | Electrophoresis in one and two dimensions and isoelectric focusing; blotting techniques; ELISA and flow cytometry; microscopy including light, fluorescence, confocal and electron microscopy; spectroscopy including UV-visible, fluorescence, NMR and mass spectrometry; X-ray crystallography; and radiolabelling and its safe handling. |
| Biostatistics, bioethics and IPR | Descriptive statistics, probability distributions, hypothesis testing, analysis of variance, correlation and regression, and experimental design; bioethics and biosafety guidelines and containment levels; intellectual property rights, patents and the regulatory framework for genetically modified organisms; and the ethics of human and animal research. |

BET is a single three-hour paper in English with two sections. Section A carries 50 compulsory multiple-choice questions pitched at 10+2 level, which function as the screening and aptitude block. Section B offers 150 questions at graduate and postgraduate biotechnology level, of which the candidate answers any 50, so selection strategy matters as much as coverage. BINC runs as a three-stage assessment instead: a preliminary objective paper, then a subjective descriptive paper for those who clear it, and finally a computer-based practical stage that tests hands-on bioinformatics work including programming.
For BET, a four-year eight-semester bachelor's degree in biotechnology, life sciences or an allied research-oriented field with at least 75% marks, with a five per cent relaxation available; or a B.Tech or B.E. with 60% for General, EWS and OBC candidates and 55% for SC, ST and differently-abled candidates; or a master's degree — M.Sc., M.Tech., M.V.Sc., M.Pharm. or MBBS — with 60%, relaxed to 55% for reserved categories. The upper age limit is 28 years for General and EWS candidates, 31 years for OBC non-creamy-layer candidates and 33 years for SC, ST, differently-abled and women candidates. For BINC, students in the final year of, or holding, a bachelor's or master's degree in life sciences, physical sciences, chemistry, mathematics, agriculture, veterinary science, pharmacy, engineering or technology may apply.
BET is held once a year, with a single national test window in May. BINC is held once a year as well.
