A number of text books are commercially available on the polymerase
chain reaction (PCR), its types and applications but these books are far
away from the approach of the students due to their high cost. The
purpose of this book is to provide the authentic material to the
students in affordable price. A very simple language is used in the book
so easy to understand. This book covers the basic principle, reagents,
equipment and methodology of the PCR. Furthermore this book also covers
optimization of various parameters for the improvement of the PCR
product. Different types of PCR and its applications in various fields
have been discussed in detail. This book is an easy way to study the
most of aspects of PCR. At the end I am thankful to the contributing
authors for sparing their time and writing a chapter on a specific topic
for this book.
