CUET 2025 Biology Syllabus

Knowledge of the CUET Biology syllabus 2025 is essential for passing the India-level test. The same is true for the CUET 2025 exam.

Most students have yet to discover the CUET Biology syllabus 2025. Here is a list of distinct units, chapters, and themes in Zoology and Botany.

Chapter-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 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).
2.

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 projects (Human and rice genomes); DNA fingerprinting. Chapter-6: Evolution – Origin of life; biological evolution and evidences (paleontology, comparative anatomy, embryology, molecular evidences); Darwin's contribution; modern synthetic theory of evolution; mechanisms – variation (mutation and recombination) and natural selection with examples, types of natural selection; gene flow and genetic drift; Hardy-Weinberg principle; adaptive radiation; human evolution.
3.

Chapter-8: Microbes in Human Welfare – Role of microbes in food processing, industrial production, sewage treatment, energy generation; use of microbes as bio-control agents and bio-fertilizers; antibiotics – production and judicious use.
4.	Biotechnology and its Applications	Chapter-9: Biotechnology: Principles and Processes – Genetic Engineering (Recombinant DNA Technology). Chapter-10: Biotechnology and its Applications – Application of biotechnology in health and agriculture: human insulin and vaccine production, stem cell technology, gene therapy; genetically modified organisms (Bt crops); transgenic animals; biosafety issues, biopiracy and patents.
