26. Suppose the two guanosine (G) nucleotides in #3 above were changed to two cytosine (C) nucleotides. What is the new amino acid chain?

This question is incomplete

Explanation:

This question is incomplete but the completed question can be found in the attachment below.

During protein synthesis, a sequence of three mRNA nucleotides (called codons) correspond to specific amino acids. From the question, the change in guanosine nucleotides will change the sequence as follow

DNA:  T--A--C--A--A--C--T--A--C--T--T--C--T--T--T--C--T--T--A--A--A

mRNA:             A--U--G|-U--U--G|-A--U--G|-A--A--G|-A--A--A|-G--A--A|-U--U--U

Amino Acids:       met --     leu   --   met   --  lys    --   lys    --    Glu   --  Phe

The new amino acid sequence is represented above from the new DNA sequence.

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.
