In the last decade, there had been a tremendous development in Biological Sciences, which resulted in the introduction of other new branches such as molecular biology, bioinformatics etc. The practical study is the main supplement to the theoretical classroom knowledge. It helps to understand the subject more precisely and accurately. In recent years many novel methods have been developed, which needed much more knowledge in practical fields. The comprehensive practical training for any student studying biological science is must. Though many practical books are available in the market but this is an unique combination of protocols that covers maximum of the practicals of various Indian universities for UG and PG courses in biological science. This book is intended to fulfill the accurate and long felt need of students of biological science. While preparing this laboratory manual the efforts have been made into various aspects of laboratory practices for the beginners. The book has been divided into 8 sections i.e. Plant Physiology, Biochemistry, Molecular Biology, Cytogenetics, Plant Tissue Culture, Microbiology, Bioinformatics and Herbarium Techniques.
