Written by David E. Newton, an author and former teacher who has dedicated a lifetime to authoring educational texts on science and technology, this book examines the history of DNA technology from its discovery in the 1950s to the present day and covers recent advances, such as new methods for gene editing, including CRISP-Cas9 technology. Readers need to have little or no background knowledge of the technology of genetic engineering to improve their understanding of DNA-based technologies and how DNA research influences many current issues and debates in agriculture, food science, forensics, public health, and other fields. The single-volume work is particularly well-suited to students and young adults because of the range of references included that serve further study, such as a glossary of terms, a chronology, and an extensive annotated bibliography.
