Biology - Biotechnology - Principles and Processes

Practise 17 NEST (NISER) previous year questions on Biotechnology - Principles and Processes, compiled from papers spanning 2011 to 2026. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty NEST (NISER) tests.

Biotechnology - Principles and Processes has been asked in 11 of the 16 years of NEST (NISER) papers analysed (2011–2026), with 17 questions in all. 18% of them were easy, 71% moderate and 12% tough. Most of its questions came from 2024, with 3 questions that year. In the last three years (2024–2026) it had 4 questions across 4 papers, about 1 per paper.

The chapter's 3 topics are not weighted equally: Tools of Recombinant DNA Technology (14 questions, 82%), Principles of Biotechnology (2 questions, 12%), and Conceptual Development of Genetic Engineering (1 question, 6%) have been asked the most. Tools of Recombinant DNA Technology has also led over the last five years, with 8 questions. Tools of Recombinant DNA Technology has produced the most tough questions (2).
