Suppose that frog embryos were genetically manipulated so that the epidermal cells expressed both E-cadherin and N-cadherin on their cell surface
The neuronal tissue and epidermal tissues were collected from the embryos and treated as illustrated in Figure 10.15b. Which of the following would you predict would happen now that N-cadherin is also present on the surface of the epidermal cells? A. The modified epidermal cells would adhere to each other and to neuronal cells. B. The genetically modified epidermal cells would adhere to neuronal cells and would no longer adhere to epidermal cells. C. The epidermal cells would adhere to each other, and not to the neuronal cells, because they would still be epidermal cells regardless of the presence of an additional cell adhesion protein on their surface.
