A screen has identified a mutant cell that is unable to migrate along the basal lamina. Sequence analysis reveals the presence of two mutations in the transmembrane domain of integrin alpha 6, that normally localizes to the plasma membrane, and which plays a critical role in cell adhesion. The mutations are as follows: Leu --> Asp and Trp --> Lys. Which of the following statements best describes a reason for why the mutant cell does not migrate in a fibronectin-coated dish? The cell does not migrate because a. the cell cannot form desmosomes b. the cell cannot form an adhesion belt c. the cell cannot form the branched actin cytoskelton at the leading edge d. the cell cannot adhere to the fibronectin that has been used to coat the dish e. The cell is unable to link its actin to the ECM via cadherins
