Recombinant human growth hormone (hGH), produced by bacteria carrying a cloned hGH gene, is a way of obtaining hGH for patients who have defective hGH genes. The hGH gene encodes an mRNA only 573 nucleotides long, but the entire gene spans more than 7000 nucleotides. There are two exons and three introns. If we were to clone this gene directly from the nuclear DNA, bacteria would not be able to express the hGH protein. Explain why this is true.

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.

explanation:

on disadvantage of hydroelectric power is the cost. another disadvantage of using hydroelectric power is finding a water source powerful enough to harvest hydroelectric power.

c.more precipitation,but only when emission levels.

i dont know it at allnow im just getting points at this pint
