I: | Transgenic animals can be specifically designed to allow study of how genes are regulated, and how they affect the normal functions of the body and its development. |
II: | Transgenic animals cannot be used to serve as models for humans diseases so that investigation of new treatments for diseases is made possible. |
III: | Transgenic animals can be specifically designed to allow study of complex factors involved in growth such as insulin like growth factor. |
