The fundamental aim underlying Cellular and Biochemical Sciences is to emphasize diversified topics of current interest to postgraduate students pursuing different courses in the area of biological sciences including Zoology, Botany, Biochemistry and Biotechnology. The text is also relevant to the students of Life Sciences, Biosciences, Cell Biology, Bioengineering and Pharmacology. A total of 58 topics have been incorporated in the book and some of the topics are rarely found in other books of Biology. New information has been introduced which updates existing knowledge and enables the book to justify its claim as the most comprehensive text in the sphere of cellular and biochemical sciences at the postgraduate and competitive examination levels. Each and every chapter has been designed in lucid and readable manner. There are references, suggested readings, long questions and objective questions at the end of chapters for revision of topics.
