Which strand of mRNA would be made during transcription using the DNA strand shown below?
GTT ACC
O A. CUU AGG
B. CTT AGG
C. CTT ACC
D. CAA UGG
ISBN

The correct answer is D. CAA UGG

Explanation:

According to the rule of base pairing the Adenine make complementary base pairing with thymine and thymine with adenine and guanine and cytosine base pairs with each other in DNA.

In RNA in place of thymine, uracil base pairs with the adenine. Therefore according to this base-pairing rule, the DNA strand GTT ACC will give rise to transcript CAA UGG. So in place of adenine uracil has come.  

Therefore the correct answer to this question is D. D. CAA UGG

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.
