An Introduction to Biotechnology: A Genetic Manipulation Perspective contains practical exercises, and has a comprehensive coverage on the subjects of biotechnology and gene manipulation for the students’ understanding of the basic concepts. This manual contains, in particular, the techniques, protocols and practical approaches that are being used routinely in molecular biology laboratories. This book is assembled together with an aim to enlighten the readers with the complex molecular biology protocols in a simple and straightforward manner. In addition, this manual also introduces readers to the study of gene manipulation in Gram-negative as well as Gram-positive bacteria. All these methods and protocols have been regularly used in the editor’s laboratory and have been modified from time to time. This practical handbook overcomes the limitations of other manuals by providing an in-depth methodology in a systematic way, blending the underlying theoretical aspects, thus facilitating the readers in understanding the reason behind every step followed during the experimental work.
