Which among the following technique is used in the treatment of a genetic disorder by insertion of a normal gene copy into an affected individual?
Answer & explanation
Correct answer: option 2
Gene therapy is a collection of methods that allows correction of a
gene defect that has been diagnosed in a child/embryo. Here genes
are inserted into a person’s cells and tissues to treat a disease.
Correction of a genetic defect involves delivery of a normal gene into
the individual or embryo to take over the function of and compensate
for the non-functional gene.
