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: -Gene therapy is a medical approach that treats or prevents disease by correcting the underlying genetic problem. Gene therapy techniques allow doctors to treat a disorder by altering a person’s genetic makeup instead of using drugs or surgery.
Detailed explanation-3: -Genetic therapies are approaches that treat genetic disorders by providing new DNA to certain cells or correcting the DNA. Gene transfer approaches, also called gene addition, restore the missing function of a faulty or missing gene by adding a new gene to affected cells.
Detailed explanation-4: -Viruses are currently the most commonly used vectors in gene therapies because they have a natural ability to deliver genetic material into cells. Before a virus can be used to carry therapeutic genes into human cells, it is modified to remove its ability to cause infectious disease.
Detailed explanation-5: -Several types of viruses, including retrovirus, adenovirus, adeno-associated virus (AAV), and herpes simplex virus, have been modified in the laboratory for use in gene therapy applications.
