Biology - Cell Cycle and Cell Division

Practise 8 IAT (IISER) previous year questions on Cell Cycle and Cell Division, compiled from papers spanning 2017 to 2025. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty IAT (IISER) tests.

Cell Cycle and Cell Division has been asked in 7 of the 9 years of IAT (IISER) papers analysed (2017–2026), with 8 questions in all. 50% of them were easy, 50% moderate and 0% tough. Most of its questions came from 2024, with 1 question that year. In the last three years (2023–2026) it had 2 questions across 3 papers, about 0.7 per paper.

The chapter's 4 topics are not weighted equally: Meiosis (3 questions, 38%), M-phase (Mitotic Phase) (3 questions, 38%), and Cell Cycle Involves Two Stages (1 question, 13%) have been asked the most. Over the last five years the most frequent topics have been M-phase (Mitotic Phase) (3) and Meiosis (1).
