Answer:
Asparagine because it is an amino acid structurally similar to the Glutamine and both have the same charge (polar neutral).
Explanation:
Glutamine (Gln or Q) is an amino acid similar to the glutamic acid, with the exception that the carboxylic acid group is replaced by an amide. In addition, glutamine, serine, threonine and asparagine are polar neutral amino acids.
Asparagine and glutamine have a similar chemical structure due to both amino acids contain amide groups in the side chain (both are dicarboxylic amides), thereby a substitution involving these amino acids will have few deleterious effects on the resulting protein.
A conservative substitution is a replacement where the modification is produced by substituting amino acids with similar biochemical properties (in this case, polar neutral).

I think the answer is C. .
The appropriate sequence of steps involved in recombinant DNA technology are as under :-
1) Selected gene is isolated.
2) Restriction enzymes cut DNA into fragments.
3) Fragments of DNA are inserted into a vector.
4) Vector and recombinant DNA multiply.
5) Recombinant DNA is inserted into host.
In the very first step, the desired gene/genetic material for cloning is isolated from the cell. To do this the cell is lysed. Cells can be lysed by sonication or using chemicals like detergents.
In the second step, isolated DNA/gene is cut with the help pf biological scalpels known as restriction enzymes. The vector (usually it is a plasmid) is also cut down using restriction enzymes.
In the third step, the fragment of the restriction digested DNA (gene) and the vector are ligated together.
In the fourth step, this vector in which desired gene has been incorporated is cloned to generate various copies.
In the last step, this recombinant DNA is inserted into a host cell where is expressed i.e. in host cell this desired gene produces its product (protein).

The correct option is (C) The neuron’s membrane voltage becomes more positive.
The resting neuron has a voltage across its membrane which is called the resting membrane potential. There is a concentration gradient of ions across the membrane when the neuron is in the resting state.
Inside the membrane the concentration of K⁺ and organic anions are more. Outside the membrane the concentration of Na⁺ is more. The membrane is much more permeable to K⁺ than Na⁺ .
The cell’s inside is more negative than the outside when the membrane is hyperpolarized. In neurons the resting membrane potential is close to the equilibrium potential for K⁺.
