Correct answer

C. introduction of gene for adenosine deaminase in persons suffering from Severe Combined Immuno-deficiency (SCID

Step-by-step solution

On September 14, 1990 researchers at the U.S. National Institutes of Health performed the first (approved) gene therapy procedure on four-year old Ashanti DeSilva. Born with a rare genetic disease called severe combined immune deficiency (SCID), she lacked a healthy immune system, and was vulnerable to every passing germ. Children with this illness usually develop overwhelming infections and rarely survive to adulthood. In this gene therapy procedure, doctors removed white blood cells from the child's body, let the
