CUET UG Biology Syllabus 2025: Syllabus, Pattern and Preparation Tips

CUET UG Biology Syllabus 2025

The Common University Entrance Test (CUET) is an undergraduate entrance exam conducted by the National Testing Agency (NTA) for students seeking admission to various universities and colleges across India. For the academic year 2025, the NTA will conduct the CUET UG exam from May 8, 2025, to June 1, 2025, in Computer-Based Test (CBT) mode. Candidates aspiring to pursue undergraduate courses that require Biology as one of the domain subjects must refer to the CUET Biology Syllabus for better preparation. The CUET UG 2025 application form has already been released, and the NTA will soon announce the CUET Biology exam date 2025 on its official website. Candidates are advised to stay updated with the latest announcements.

The CUET UG Biology syllabus is designed according to the NCERT Class 12 Biology syllabus and consists of five broad units. Here's the full detailed CUET UG Biology Syllabus below-

Unit I: Reproduction

Chapter 1:Sexual Reproduction in Flowering Plants Flower structure; development of male and female gametophytes; pollination - types, agencies and examples; out breeding devices; pollen-pistil interaction; double fertilization; post fertilization events - development of endosperm and embryo, development of seed and formation of fruit; special modes- apomixis, parthenocarpy, polyembryony; Significance of seed dispersal and fruit formation

Chatpter 2:Human Reproduction Male and female reproductive systems; microscopic anatomy of testis and ovary; gametogenesis -spermatogenesis and oogenesis; menstrual cycle; fertilisation, embryo development upto blastocyst formation, implantation; pregnancy and placenta formation (elementary idea); parturition (elementary idea); lactation (elementary idea).

Chapter 3:Reproductive Health Need for reproductive health and prevention of Sexually Transmitted Diseases (STDs); birth control - need and methods, contraception and medical termination of pregnancy (MTP); amniocentesis; infertility and assisted reproductive technologies - IVF, ZIFT, GIFT (elementary idea for general awareness).

Unit II: Genetics and Evolution

Chapter 4:Principles of Inheritance and Variation Heredity and variation: Mendelian inheritance; deviations from Mendelism – incomplete dominance, co-dominance, multiple alleles and inheritance of blood groups, pleiotropy; elementary idea of polygenic inheritance; chromosome theory of inheritance; chromosomes and genes; Sex
determination - in humans, birds and honey bee; linkage and crossing over; sex linked inheritance - haemophilia, colour blindness; Mendelian disorders in humans - thalassemia; chromosomal disorders in humans; Down's syndrome, Turner's and Klinefelter's syndromes.

Chapter 5:Molecular Basis of Inheritance Search for genetic material and DNA as genetic material; Structure of DNA and RNA; DNA packaging; DNA replication; Central Dogma; transcription, genetic code, translation; gene expression and regulation - lac operon; Genome, Human and rice genome projects; DNA fingerprinting.

Chapter 6:Evolution Origin of life; biological evolution and evidences for biological evolution (paleontology, comparative anatomy, embryology and molecular evidences); Darwin's contribution, modern synthetic theory of evolution; mechanism of evolution - variation (mutation and recombination) and natural selection with examples, types of natural selection; Gene flow and genetic drift; Hardy- Weinberg's principle; adaptive radiation; human evolution.
