Overview


Students are introduced to the structure and function of cells and to the different types and purposes of cell division: growth, repair, and reproduction. They are familiarized with basic principles governing inheritance, and learn about the basic structure of DNA. Students also will read and discuss a case study involving a controversial application of DNA research.
