A scientist observes a mutation in the transmembrane region of EGFR that eliminates its ability to be stabilized by binding interactions during dimerization after ligand binding. Which hypothesis regarding the effect of this mutation on EGF signaling is most likely to be correct? a. EGF signaling cascades would be active for longer in the cell. b. EGF signaling cascades would be active for a shorter period of time in the cell. c. EGF signaling cascades would not occur. d. EGF signaling would be unaffected.
