Recombinant DNA Technology focuses on the current state of knowledge on recombinant DNA (rDNA) technology and its applications. The book provides comprehensive information on the principles and concepts of rDNA technology or genetic engineering, protein expression of cloned genes, polymerase chain reaction (PCR) amplification of DNA, restriction fragment length polymorphism (RFLP), amplified fragment length polymorphism (AFLP), DNA fingerprinting, and the most recent siRNA technology. It is useful for post-graduate students and teachers in the areas of molecular biology, biotechnology, genetics, microbiology, life sciences, pharmacy, agriculture, and basic medical sciences.
