Answer:
D. Scientists use viruses to insert specific gene sequences.
Explanation:
Gene Therapy:
- Gene therapy is a treatment approach for genetic diseases that involves either the removal or the replacement of the defective gene with a normal one.
- Gene therapy is currently an experimental procedure that utilizes <em>in-vivo</em> (directly into body) and <em>ex-vivo</em> (taking cells outside, treating them and injecting them back into the body.
- Gene therapy involves the use of two kinds of vectors i.e. vehicles for carrying and injecting the normal gene into body cells:
- <u>Viral vectors are modified viruses that infect the target cells and inject the normal gene in to them.</u>
- Non-viral vectors mostly comprise polymers (such as lipid based particles etc.) that encapsulate the normal gene and fuse with the cell membrane of the target cells.

regulation in the human body. The role of vitamin D is shown in orange. Vitamin D is carried in the bloodstream to the liver, where it is converted into the prohormone calcifediol. Circulating calcifediol may then be converted into calcitriol, the biologically active form of vitamin D, in the kidneys.
