Question

Quizplus · Accepted Answer

The retrovirus is used to insert a functional version of a missing gene in the patient's skin cells. This altered skin is then transplanted into the patient's body. If all goes well, the graft will be accepted by the patient's immune system and secrete the protein product of the inserted gene. Option A, C, D, and E are incorrect because the retrovirus is used to insert a functional gene, not activate an abnormal gene or lead to apoptosis.
