PATHOLOGY

Detailed explanation-1: -Gene therapy is a technique that modifies a person’s genes to treat or cure disease. Gene therapies can work by several mechanisms: Replacing a disease-causing gene with a healthy copy of the gene.

Detailed explanation-2: -Gene replacement therapy is the technique of recognizing a faulty gene, applying a piece of DNA in its correct form though a viral vector (known as the carrier molecule) to the gene, thus overriding the identified faulty gene with the correct copy.

Detailed explanation-3: -Procedure Details With gene therapy, doctors deliver a healthy copy of a gene to cells inside the body. This healthy gene may replace a damaged (mutated) gene, inactivate a mutated gene or introduce an entirely new gene. Carriers, called vectors, transport these healthy genes into cells.

Detailed explanation-4: -A gene mutation (myoo-TAY-shun) is a change in one or more genes.
