A bland but serviceable text explains basic information about genetics and the role of DNA in creating life. Cramped with charts, color photos, and captions, the double-page spreads touch on related topics such as genetic engineering, cloning, and using DNA to solve crimes. Each chapter ends with an unnecessary summary highlighting key issues already discussed in the main text. Websites. Glos., ind. From HORN BOOK Spring 2004, (c) Copyright 2010.
