Topics For Preparation: The National Eligibility cum Entrance Test for Undergraduates (NEET-UG) stands as one of the most challenging examinations in India, drawing candidates who aspire to gain admission to medical and dental institutions. However, the biology section, which constitutes 50% of the exam syllabus, plays a pivotal role in determining candidates’ rankings. Below are the top 10 essential biology questions as well as concepts to concentrate on for NEET UG 2025, along with effective preparation strategies to achieve success.
Topics For Preparation: Structure of DNA and RNA
- Expected Question: Discuss the structural and functional distinctions between DNA and RNA.
- Importance: Molecular biology is a crucial topic, with questions often focusing on the structure, function, and replication of nucleic acids.
- Preparation Tip: Familiarize yourself with the Watson-Crick Model, base pairing, and the various types of RNA (mRNA, tRNA, rRNA).
Photosynthesis and Cellular Respiration
- Expected Question: Describe the function of the Calvin cycle in photosynthesis and compare it to glycolysis in cellular respiration.
- Importance: These processes are fundamental to the understanding of metabolism.
- Preparation Tip: Concentrate on the key steps, enzymes, and energy transformations involved in both processes.
Human Physiology: Endocrine System
- Expected Question: Explain how hormones regulate blood glucose levels.
- Importance: Questions regarding feedback mechanisms and hormonal functions commonly encountered.
- Preparation Tip: Memorize the names of hormones, their sources, target organs, and the associated feedback mechanisms.
Genetics and Mendelian Inheritance
- Expected Question: Solve a dihybrid cross problem and determine the phenotypic ratios.
- Importance: Genetics questions assess analytical and application skills.
- Preparation Tip: Practice using Punnett squares, conduct pedigree analyses, and study exceptions to Mendel’s laws, such as codominance and multiple alleles.
Evolution and Origin of Life
- Anticipated Question: Summarize the evidence that supports Darwin’s theory of natural selection.
- Significance: The concept of evolution often assessed for both its theoretical understanding and historical relevance.
- Study Advice: Review instances such as industrial melanism, homologous and analogous structures, as well as molecular evidence.
Topics For Preparation: Human Reproduction
- Anticipated Question: Explain the hormonal control of the menstrual cycle.
- Significance: This subject connects human physiology with reproduction, making it a common topic in examinations.
- Study Advice: Concentrate on the functions of FSH, LH, estrogen, and progesterone, along with the phases of the cycle.
Plant Physiology: Transport in Plants
- Anticipated Question: Describe how water and minerals transported through the xylem.
- Significance: Topics such as transpiration and the cohesion-tension theory frequently evaluated.
- Study Advice: Grasp the concepts of active and passive transport, root pressure, and the process of translocation in phloem.
Biotechnology: Principles and Processes
- Anticipated Question: Explain the function of restriction enzymes in recombinant DNA technology.
- Significance: The applications of biotechnology in medicine and agriculture are of great importance.
- Study Advice: Focus on tools such as PCR, plasmids, and the use of vectors.

Ecology and Environment
- Anticipated Question: Discuss the importance of ecological pyramids and energy transfer within ecosystems.
- Importance: A solid understanding of ecology can lead to high scores, as it is largely conceptual.
- Preparation Advice: Review biogeochemical cycles, interactions among populations, and areas rich in biodiversity.
Microbes in Human Welfare
- Anticipated Question: Explain the contribution of microbes to the industrial synthesis of antibiotics.
- Importance: Microbiology encompasses both theoretical and practical questions.
- Preparation Advice: Concentrate on the roles of microbes in sewage treatment, biogas generation, and the use of probiotics.
Strategies for Biology Preparation
- Master NCERT: A significant number of NEET questions derived directly from the NCERT biology textbooks for grades 11 and 12. Thoroughly study diagrams, tables, and emphasized points.
- Practice MCQs: Regularly practicing multiple-choice questions will enhance both speed and accuracy. Utilize past exam papers and mock tests.
- Revise Regularly: Biology requires strong retention, so implement a weekly revision schedule for essential topics.
- Use Mnemonics: Employing mnemonics can simplify the memorization of intricate processes and sequences.
By concentrating on these essential questions and following a structured preparation approach, you can greatly improve your performance in the Biology section of NEET UG 2025. At last, keep in mind that consistency and a clear understanding of concepts are crucial for success!
