MCQ
Gene therapy has been successful in curing genetic diseases in laboratory animals through
  • A
    Exposure to $X-$ray to rectify the defective gene
  • B
    Replacing the defective gene with a functional gene
  • Oral delivery of genes
  • D
    Use of therapeutic medicines to rectify the defective genes

Answer

Correct option: C.
Oral delivery of genes
Gene therapy has become successful because of the main fact that it can deliver and replace a defective gene with a functional gene.
