The revised edition of this bestselling textbook provides latest and detailed account of vital topics in biology, namely, Cell Biology, Genetics, Molecular Biology, Evolution and Ecology . The treatment is very exhaustive as the book devotes exclusive parts to each topic, yet in a simple, lucid and concise manner. Simplified and well labelled diagrams and pictures make the subject interesting and easy to understand. It is developed for students of B.Sc. Pass and Honours courses, primarily. However, it is equally useful for students of M.Sc. Zoology, Botany and Biosciences. Aspirants of medical entrance and civil services examinations would also find the book extremely useful.

This book covers some of the most important subjects in biology. such as cell biology, genetics, molecular biology, evolution, and ecology, and it does so in a comprehensive and up-to-date manner. The coverage is quite detailed since the book devotes special portions to each topic while still presenting the information in a simple, clear, and succinct manner. The topic is made more exciting and simpler to comprehend via the use of diagrams and graphics that are both streamlined and well labelled. The study of the organization of cells, their structures, their physiological characteristics, their life cycles, metabolic activities, and signalling pathways, as well as how cells interact with their surroundings, is the focus of the biological discipline known as cell biology. There is an overlap with other fields like immunology, biochemistry. and developmental biology. This book makes an effort to comprehend the several subfields that comprise the field of cell biology as well as how theoretical ideas can be put into practice in the real world. Genetics is the scientific study of genes or heredity which is the process through which certain attributes or traits are handed down from parents to children as a consequence of changes in the DNA sequence. The study of the content, structure, and interactions of cellular molecules, such as nucleic acids and proteins. that carry out the biological processes needed for the cell's functioning and maintenance is the focus of the branch of biology known as molecular biology

First stated as a method for understanding the basis of biological events, molecular biology seeks to understand how organisms work by delving into the structure and function of individual molecules and how these molecules interact with one another and with the larger environment. According to this book understanding how the chemicals that make up cells impact the behavior of living things is a central goal of molecular biology and genetics. To understand how these molecules work in the dynamic environment of a live cell, biologists use a wide range of molecular and genetic techniques.These methods are being used by groups in our department to investigate a broad range of issues, including as the basic mechanisms governing transcription and translation as well as pathways involved in signal transduction. Among them are the role of the senses of sight and smell and how genetic diversity in wild populations influences evolution. Although the systems being studied include a variety of model species, including bacteria, the yeast, slime molds, worms, the fruit flies, zebrafish, and mice, the findings from these research have some direct or indirect relevance to human health. This book covers the key topics in cell biology, genetics, molecular biology, evolution, and ecology, such as the structure and function of nucleic acids, a general review of cells, and DNA replication with knowledge of genetics and their evolutionary histories.

This book is especially prepared for the students of B.Sc. and M.Sc. of different Indian Universities as per UGC Model Curriculum. Students, preparing for Medical Entrance Examination, IAS, IFS, and PCS etc. will also be benefited by this book. At the end of some chapters of Genetic Engineering may enlighten the target readers. Entirely new information on Quantitative Genetics and Immunogenetics may enthral the readers. MCQ's ans answers will also be helpful for the students to strngthen their self confidence. By the help of numerous figures, many tables, boxes and coloured photographs, this book has tried to serve a balanced account of Classical Genetics and Modern Molecular Genetics. • This book is for Graduate, P.G. students of Biophysics, Microbiology& Biological Sciences.

This book explains the essential principles, processes and methodology of cell biology, biochemistry and molecular biology. It reflects upon the significant advances in cell biology such as motor proteins, intracellular traffic and targeting of proteins, signalling pathways, receptors, apoptosis, aging and cancer. It also discusses certain current topics such as history of life (origin of life), archaebacteria, split genes, exon shuffling, gene silencing, RNA interference, miRNA, siRNA and recombinant DNA technology, etc.
