INTRODUCTION

This chapter provides information regarding the practical side of molecular biology. Molecular biology methods are used extensively in modern-day drug discovery, research and development, and diagnostics. In the previous chapters too, various other techniques in molecular biology such as cloning, FISH, DNA and protein arrays and DNA foot printing had been covered. This chapter focuses on the common molecular biological techniques such as electrophoresis, blotting techniques and polymerase chain reaction (PCR).
