This book is intended for those appearing for the DBT-JRF Biotechnology examination known as the Biotechnology Eligibility Test (BET). The examination is conducted by DBT, Government of India, to encourage students (B.Tech./M.Sc.) of Life Sciences disciplines to pursue research (Ph.D.) in both DBT-affiliated and non-DBT-affiliated institutes. The book is written based on the currently prescribed syllabus by DBT. The book has three sections. The first section deals with the fundamentals of General Biotechnology covering an entire syllabus of the examination. Similarly, the second section deals with the different branches of Biotechnology. Every unit of the syllabus is considered into account to frame quality questions that equalize the standard of BET examination. All the questions are answered with detailed explanations to give an insight into the fundamental concept. The third section of the book deals with more than 10 previous years? question papers with solutions. The book is also useful for the aspirants of similar examinations, viz. CSIR-NET, ICMR-JRF, ICAR-JRF, NII-Ph.D., JNU-Ph.D., IIT-JAM and TIFR-NCBS. Debasish Kar graduated in Physiology (H) from Midnapore College, West Bengal. He studied M.Sc.
