DNA is an interactive Web site where students can learn about DNA and its structure and function, the scientific history of its discovery and its development into a powerful tool in biology, technology, and medicine, and about the Human Genome Project, genetic engineering, and some of the implications and ethical issues surrounding genetic technology.

Students will be introduced to genetics (the study of genes and heredity) and genetic terminology, and will learn about the history of the study of genes and genetic inheritance. They will learn the basic laws of heredity, and employ tools for the study of genetic inheritance. Several interactive activities will expand upon this knowledge and test students’ understanding of the concepts. Through an interactive timeline, students will explore the history of DNA, and will learn about the Human Genome Project and its purpose, the differences between DNA, RNA, and proteins, and about genetic engineering. Interactive activities will illuminate more details about DNA transcription, RNA translation, and genetic engineering. Students will also examine some of the implications of and ethical questions raised by genetic technology such as cloning, gene therapy, and genetically modified food.
