CUET Biology Syllabus 2027: PDF Available; Important Chapters, Question Papers & Books

Candidates preparing for Biology exam must read the article below to know the CUET Biology Syllabus for 2027-28 admission cycle. Also get the exam pattern and recommended books to prepare for exam.

CUET Biology Syllabus

The National Testing Agency will soon release the CUET Biology syllabus for 2027-28 admission cycle on its official website. Last year, NTA curated the Biology syllabus in more detail, making it easier for candidates to know the topics included in each chapter. It is expected that the CUET Biology syllabus will remain the same this year also. With Biology, students can get admission to courses like B.Sc. (Hons) in Botany, Zoology, Biology and other specializations. To get good marks in the exam, candidates must know the CUET syllabus 2027. Biology is one of the top 10 CUET subjects. Candidates can now download the CUET Biology syllabus PDF from cuet.nta.nic.in and this page.

The syllabus includes topics such as reproduction, biotechnology, ecology and environment, health and disease, and many more. Candidates preparing for the CUET exam must check the CUET eligibility criteria to avoid disqualification during admission. NTA will conduct CUET 2027 for UG admissions in May 2027. The mode of examination will be Computer-Based Test (CBT).

CUET UG Biology Syllabus 2027

The CUET Biology Syllabus includes 5 units with multiple chapters. Candidates can take a look at the detailed CUET Biology Syllabus here.

Unit I: Reproduction 

1. Sexual Reproduction in Flowering Plants: Pre-fertilisation: structure and events - stamen, microsporangium and pollen grain, pistil, megasporangium and embryo sac; Development of male (microsporogenesis) and female gametophyte (megasporogenesis); Pollination – types, agents and examples; Out breeding devices; Pollen-pistil interaction; Double fertilisation; Post fertilisation: structure and events – development of endosperm and embryo; Formation of seed and fruit and parthenocarpy; Significance of seed in angiosperms; Apomixis and polyembryony.

2. Human Reproduction: Male and female reproductive systems; microscopic anatomy of testis and ovary; gametogenesis - spermatogenesis and oogenesis; menstrual cycle; fertilisation, embryo development up to blastocyst formation, implantation; pregnancy and embryoni development and placenta; Parturition and lactation.

3. Reproductive Health: Problems and strategies -  amniocentesis; Population stabilisation and birth control – various methods of contraception; Medical termination of pregnancy (MTP); Sexually transmitted infections (STIs); Infertility – Assisted reproductive technologies (IVF, ZIFT, GIFT, ICSI and IUI).

Unit II: Genetics and Evolution

1. Principles of Inheritance and Variation: Mendel’s law of inheritance: Inheritance of one gene – Law of dominance, law of segregation (test and back cross); Deviation from Mendelism – incomplete dominance and co-dominance; Multiple alleles and inheritance of blood groups; Inheritance of two genes – law of independent assortment, dihybrid cross; Chromosomal theory of inheritance; Linkage and recombination; Polygenic inheritance; Pleiotropy; Sex determination in humans, birds and honey bee; Mutation; Genetic disorders – pedigree analysis, Mendelian disorders (colour blindness, haemophilia, sickle-cell anaemia, phenylketonuria and thalassemia), chromosomal disorders in humans (aneuploidy, polyploidy, Down's syndrome, Turner's syndrome and Klinefelter's syndrome).

2. Molecular Basis of Inheritance:  Structure and packaging of DNA helix; Search for genetic material (transforming principle and Hershey-Chase experiment); Properties of genetic material; Replication (Meselson and Stahl’s experiment); Transcription – transcription unit and gene; RNA world – types of RNA and process of transcription; Genetic code and mutations; tRNA; Translation; Regulation of gene expression – Lac operon; Human Genome Project (goals, salient features and applications); DNA fingerprinting (polymorphism and VNTR). 

3. Evolution: Origin of life – Miller’s experiment; Concepts of evolution (Darwin's contribution); Evidences for evolution (embryology, paleontology, comparative anatomy, divergent and convergent evolution and industrial evolution); Adaptive radiation; Biological evolution; Natural selection; Mechanism of evolution; Hardy-Weinberg principle and affecting factors (gene migration, genetic drift, mutation, recombination and natural selection); Evolution of plants and vertebrates through geological periods; Origin and evolution of man.

Unit III: Biology and Human Welfare

1. Human Health and Disease: Introduction about health; Common diseases in humans (typhoid, pneumonia, common cold, malaria, amoebiasis, ascariasis, filariasis and ringworms); Immunity – innate and acquired immunity, active and passive immunity, vaccination and immunisation, allergies, auto-immunity and immune system in human; AIDS; Cancer; Drugs and alcohol abuse - adolescence, addiction, effects of drug abuse, prevention and control. 

2. Microbes in Human Welfare: Microbes in household products; Microbes in industrial products – beverages, antibiotics, enzymes and bioactive molecules; Microbes in sewage treatment and production of biogas, Microbes as biocontrol agents and biofertilisers. 

Unit IV: Biotechnology and its Applications 

1. Biotechnology: Principles and Processes: Principles of biotechnology; Tools of recombinant DNA technology – restriction enzymes, cloning vectors, competent host; Processes of rDNA technology – isolation, amplification of gene (PCR), insertion of rDNA in host and bioreactors; Downstream processing.

2. Biotechnology and its Applications: Application of biotechnology in agriculture – tissue
culture, genetically modified organisms, Bt cotton, RNA interference; Biotechnology in medicine – insulin, gene therapy and molecular diagnosis; Transgenic animals; Ethical issues – biopiracy and patents.

Unit V: Ecology and Environment 

1.  Organisms and Populations: Population attributes - birth and death rate, age pyramids; Population growth – exponential and logistic growth; Life history variation; Population interactions – predation, competition, parasitism, commensalism, mutualism and amensalism.

2. Ecosystem: Structure and function; Productivity; Decomposition; Energy flow – different trophic levels, food chain and food web; Ecological pyramids – pyramid of energy, biomass and number. 

3. Biodiversity and Conservation: Biodiversity – concept, patterns and importance; Causes of biodiversity loss; Biodiversity conservation – approaches (narrowly utilitarian, broadly utilitarian and ethical); Methods of biodiversity conservation – in situ (endemism, hotspots and sacred groves etc.), ex situ (Wildlife safaris, zoological parks and cryopreservation etc.).
