Gene therapy is an integral part of genome projects. It includes the correction of abnormal genes responsible for diseases. Which of these is an application of gene therapy?

C. The introduction of a new gene that can bind with the abnormal gene to inhibit its action.

Explanation:

Gene therapy is a new system of treatment being introduced that employs the use of genes as against drugs in the treatment of diseases. Most diseases arise as a result of a mutation in a gene. Gene therapy seeks to replace these mutated genes with healthy genes. The bad gene could also be inactivated or knocked out to prevent further damage.

So, when a new gene is introduced and made to bind with an abnormal gene to inhibit its action, that is a knockout process employed in gene therapy. The practice is still under trial.
