Zoology - Molecular Basis of Inheritance

Practise 58 JIPMER previous year questions on Molecular Basis of Inheritance, compiled from papers spanning 2004 to 2019. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty JIPMER tests.

Molecular Basis of Inheritance has been asked in 0 of the 19 years of JIPMER papers analysed (2001–2019), with 58 questions in all. 74% of them were easy, 19% moderate and 7% tough. Most of its questions came from 2019, with 0 questions that year. In the last three years (2017–2019) it had 0 questions across 5 papers, about 0 per paper.

The chapter's 11 topics are not weighted equally: Structure of DNA (11 questions, 19%), Regulation of Gene Expression (9 questions, 16%), and Transcription (8 questions, 14%) have been asked the most. Regulation of Gene Expression has produced the most tough questions (2).
