Beginning with the basic concept of gene cloning, topics such as restriction endonucleases, chemical synthesis of oligonucleotides, cDNA synthesis, plasmids, and polymerase chain reaction have been discussed in detail in this book. The book also contains separate chapters on molecular markets and public concerns. All chapters begin with the chapter objectives and provide a exhausitive recap of the important concepts at the end of the chapter followed by reviewquestions and numerical exercises. The language is extremely lucid and pertinent and interesting facts and anecdotes have also been included in each chapter which should surely hold the interest of readers.
