Explanation:
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. Inactivating a disease-causing gene that is not functioning properly.
Detailed explanation-2: -Most commonly, gene therapy uses a vector, typically a virus, to deliver a gene to the cells where it’s needed. Once it’s inside, the cell’s gene-reading machinery uses the information in the gene to build RNA and protein molecules. The proteins (or RNA) can then carry out their job in the cells.
