DNA is a double stranded nucleic acid which forms a double-helix structure made up of two chains of nucleotides, quite similar to that of a twisty ladder. RNA is only made up of a single strand of amino acids and therefore only forms a single stranded helix structure.

There are some main differences between DNA and RNA, the first one is quite simple, DNA is made out of a double ribbon, and RNA is made out of a single one. But this is not the only difference, and not even the main one. The main difference is at their content, DNA includes some nucleotides , they are cytosine (C), thymine (T), adenine (A), guanine (G), but on RNA it's a little bit different. Instead of a thymine, there's a new nucleotide called uracil (U). By that information we can rearrange the base pairs, in DNA it's (A-T) and (C-G), but in RNA it's (A-U) and (C-G).

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.

Why is earth's outer core hotter than earth’s oceanic crust? earth’s oceanic crust is denser than earth’s outer core is. earth’s oceanic crust has lava flowing from the mantle. earth’s outer core has a composition of solid iron and nickel. earth’s outer core is deeper within earth than oceanic crust is.
