Assume a mutation of the gene coding for the voltage-gated sodium channel resulted in channels that do not have the ball and chain part of the protein. Which of the following would you expect to see? a. A change in the ion selectivity of the channel of the mutated channels, allowing ions other than sodium to move through it. b. A change in the voltage sensitivity of the channel so that it does not open until more depolarized voltages. c....
