Which mutation(s) would not change the remainder of the reading frame of a gene sequence that follows the mutation(s)? which mutation(s) would not change the remainder of the reading frame of a gene sequence that follows the mutation(s)? one deletion mutation. one addition and two deletion mutations. one addition mutation. one addition and one deletion mutation?

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
