Detailed explanation-1: -In what way did gene therapy, the replacement of a faulty gene with a normal one, stimulate medical research? The genes on each chromosome had to be mapped and described. The human genome project mapped out each gene of humans making gene therapy possible.
Detailed explanation-2: -The earliest method of gene therapy, often called gene transfer or gene addition, was developed to: Introduce a new gene into cells to help fight a disease. Introduce a non-faulty copy of a gene to stand in for the altered copy causing disease.
Detailed explanation-3: -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.
