National Entrance Screening Test (NEST) is a compulsory test for students seeking admission to National Institute of Science Education and Research (NISER) Bhubaneswar and University of Mumbai – Department of Atomic Energy Centre for Excellence in Basic Sciences (UM-DAE CEBS), Mumbai.
NEST 2020 will be conducted in around 90 cities across India.
There is no specific syllabus for the General section. The aim is to test candidate’s aptitude for a career in science. Questions are designed to test the candidate’s familiarity with (but not a detailed understanding of) major historical milestones in Mathematics, Physics, Chemistry, Biology, Astronomy, Computer science and Environmental studies.
There will be some questions designed to test the grasp of Mathematics up to 10th standard and application of the same to simple problems. Some questions in this section aim to test the candidate’s general ability to comprehend qualitative and quantitative aspects of a given scientific passage.
This is done by giving a passage on some scientific topic and questions based on the concepts elaborated in the passage will be asked. Some questions may aim to find whether the candidates can interpret graphical and/or tabular representation of information.
Cell theory and cells as unit of life. Basic concepts of biomolecules – Proteins, Carbohydrates, Lipids, Nucleic acids. Tools and techniques of cell studies – use of microscope and calibration (microscopy), elements of microscope. Biomembranes – transport mechanism, cellular respiration.
Cell organelles – structure and functions. Discovery and structure of DNA, processes of replication, transcription, genetic code and translation. Principles of the basic techniques in molecular biology. Enzymes– catalysis, kinetics, activation energy, competitive and non– competitive inhibition.
