This book is for CSIR JRF NET LIFE SCIENCES and other entrance examinations.

This book will also cater to the need of students preparing for other competitive exams such as ICAR, ICMR, GATE, TIFR, DBT, IISc, JNU, DU, BHU, M.Sc. Indian Civil Services, Indian Forest Services (IFS), Provincial Civil Services (PCS)  etc. Although the book is designed keeping in mind the CSIR- UGC syllabus for Life Sciences, however, the undergraduate and post-graduate students of various universities across the country will also find this book useful.

The book is simple and has been designed as per the latest syllabus. For the ease of understanding the book is organized into 13 chapters within IV Volumes. This book, the volume I of the series concentrates on the first three units of the syllabus, namely: 


The book is simple and has been designed as per the latest syllabus. For the ease of understanding the book is organized into 13 chapters within IV volumes. This book, the Volume VI of the series concentrates on the 11th, 12th and 13th units of the syllabus. An honest effort has been made to cover and provide updated information in all the sections and subsections under each unit so as to enrich the knowledge and understanding of the students in related topics. 

The content of the volumes are:
