Developed by teachers, this kit aids students in understanding the principles of recombinant DNA technology. It consists of teacher demonstration models and student manipulative sets, sufficient for a classroom of thirty students. Using the manipulatives, students learn the process of recombinant DNA technology. Plasmid DNA is cut with restriction enzymes and recombinant plasmids are formed. Lasminated teacher and student gel electrophoresis boards are also included. Our kit allows students to learn DNA technology without the need for expensive laboratory equipment. Kit contains no consumable parts. It can therefore be used over and over again, and/or can be shared by the entire science department. Includes 78 peices of specially designed plastic manipulatives. Also included are a manual and instructional videotape in which an experienced teacher demonstrates use of the manipulatives included in the kit. Shipping weight 8 lbs., dimensions 22 x 17 x 4.
