Summary:

Diagnostic Techniques in Genetics offers a comprehensive coverage of the theory and practice of the molecular biology techniques used within medical genetics. The first part of the book focuses on DNA/RNA applications and includes many of the latest developments in the field combined with routine procedures of genetic diagnoses, for example cloning and sequencing DNA. The DNA applications presented are then each applied to a specific kind of genetic diagnosis and the text concludes with a chapter devoted to population genetics.

The book provides a broad overview of the fundamental theory and applications used in the diagnosis of numerous genetic diseases. Each chapter has been written by leading professionals in the field and is intended to show how molecular biology (DNA or RNA technology) may be applied to a large set of genetic diagnoses. comprehensive coverage of DNA applications and genetic diagnoses, includes a chapter on population genetics, essential reading for students taking courses in medical genetics, medicine and molecular biology.
