Question

________ is a technique that involves putting a healthy copy of a gene into cells that have a defective copy of the same gene.

Answer 1

Gene Therapy

Step-by-step explanation:

Gene Therapy:

Gene therapy is an experimental treatment for genetic disorders that involves removing or replacing a defective or mutated gene with a healthy one.

This technique uses viral and no-viral vectors to insert the healthy copy of a faulty gene into target cells. Extensive research is being conducted on making these vectors safer and bio-compatible (in case of synthetic non-viral vectors).

This is achieved through the application of two methods:

1. In-vivo gene therapy that involves injecting the healthy gene itself or the vector containing the healthy gene into the patient's body.
2. Ex-vivo gene therapy that extracts the affected cells from the body and infects them with the healthy gene containing virus. The cells with the new, healthy gene are then grafted back into the body.
