The right answer is D.
Gene therapy is a method of introducing nucleic acids (DNA or RNA) into the cells of an organism to correct an abnormality, such as a mutation, causing a pathology.
It is often a question of bringing a normal and functional gene (transgene) into a cell where the present gene is altered.
Another method can bring RNA capable of partially regulating or blocking the expression of an altered gene.

<span>R group (or side chain) is an organic component of amino acids that is unique to each amino acid. </span> <span>Three of the amino acids have basic side chains at neutral pH: arginine (Arg), lysine (Lys), and histidine (His). Their side chains contain nitrogen and resemble ammonia, which is a base and their pKa's are high enough that they tend to bind protons, (positive charge). Aspartic acid or aspartate (Asp) and glutamic acid or glutamate (Glu) are acidic amino acids because their side chains have carboxylic acid groups whose pKa's are low enough to lose protons, (negatively charged). The non-polar amino acids contain uncharged functional groups<span> at physiological pH and are incapable of participating in hydrogen bonding. </span></span>
