Useful for teaching AP Biology units on molecular genetics, this manipulative can be used to show how genes are “turned off and on” to prevent waste of energy and resources, as well as to demonstrate concepts of proteins, enzymes, and gene expression. -- Students label and define all parts of the operon and walk through the steps of the operon when it is considered on and off. This can then be tied into lessons on positive and negative feedback loops. Developed by Carol Bullock. -- Includes: colored metal paper clips, two feet 3/16” vinyl tubing, two feet 1/4” vinyl tubing, electrical tape, set of 15 labels, 15 wooden dowels, thread, Demonstration video tape, instructions. |
