The book entitled “Basic Concepts of Plant Biotechnology (with MCQs)” has been publishing when the recombinant DNA and sequencing of human and many plant genomes have been completed. This book contains almost 3000 multiple choice questions as well as fill in the blanks with answers covering all aspects of molecular biological systems of prokaryotes and eukaryotes. In writing the first edition, the aim is to provide all simple and difficult questions for weak students in plant molecular biology that have no more knowledge and have more problems in solving the questions. Therefore, in this book we included questions belongs to all basic concept of molecular biology which will provide strong knowledge to students preparing for competitive exams of life science like CSIR-NET, DBT-JRF, ICMR-JRF, ICAR-NET, ARS, PSC, graduate and post-graduate exams.
