"Genetic engineering, and related research, is helping to shape the future of humankind. Over the past two decades scientists have made impressive breakthroughs. They have used the technology to discover cures for diseases, solve crimes, and develop drought-resistant crops that can be used to feed millions of people. However, not everyone is excited about the potential benefits of this technology. Some people believe that it is not right for scientists to "interfere" with nature; others are concerned about unknown health issues related to genetically modified organisms. These are difficult but intriguing ethical issues. This book will examine the science behind genetic engineering, discuss how scientists work with and modify genetic information, and explore some of the questions this new science raises. Each title in this series includes color photos throughout, and back matter including: an index and further reading lists for books and internet resources. Key Icons appear throughout the books in this series in an effort to encourage library readers to build knowledge, gain awareness, explore possibilities and expand their viewpoints through our content rich non-fiction books. Key Icons in this series are as follows: Words to Understand are shown at the front of each chapter with definitions. These words are set in boldfaced type in that chapter, so that readers are able to reference back to the definitions--building their vocabulary and enhancing their reading comprehension. Sidebars are highlighted graphics with content rich material within that allows readers to build knowledge and broaden their perspectives by weaving together additional information to provide realistic and holistic perspectives. Educational Videos are offered in chapters through the use of a QR code, that, when scanned, takes the student to an online video showing a moment in history, a speech, or an instructional video. This gives the readers additional content to supplement the text. Text-Dependent Questions are placed at the end of each chapter. They challenge the reader's comprehension of the chapter they have just read, while sending the reader back to the text for more careful attention to the evidence presented there. Research Projects are provided at the end of each chapter as well and provide readers with suggestions for projects that encourage deeper research and analysis. And a Series Glossary of Key Terms is included in the back matter containing terminology used throughout the series. Words found here broaden the reader's knowledge and understanding of terms used in this field."
