What does DNA provide the code for? A nitrogenous base pairing
B protein synthesis
C deoxyribose formation
D nucleotide synthesis
answer is protein synthesis

the answer is actually B (protein synthesis) !!

Explanation:

i just took the practice test on edge and it was right !!

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.
