This teacher-developed DNA Manipulatives Kit is just what is needed for students to understand recombinant DNA technology. Kit combines real world applications such as human insulin produced from E. coli bacteria with both instructor demonstrations and hands-on student activities. Kit includes magnetic teacher manipulatives designed to be used on the chalk board and student sets. Using the manipulatives, students learn about the structure and function of DNA (chromosomal and plasmid), and insert antibiotic resistant genes into plasmids. The manipulative plasmids include information on the number of base pairs, and lessons about restriction enzymes. Also includes experiments using laminated teacher and student gel electrophoresis boards and an instructional CD. The teacher board is large enough to be seen by the class for demonstrations. Students use a set of 15 boards.
