Rna polymerase binds to template strand of dna.
a. initiation
b. elongation
c. termination

a. initiation, b. elongation and c. termination

Explanation:

RNA polymerase binds to the promoter region of DNA where transcription is initiated, then addition of nucleotides commences, the elongation stage. Finally once it has transcribed the terminator region of the DNA, trancription stops (termination).

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.
