Practicing Success
Read the paragraph given below and answer the question. If a person is born with a hereditary disease, can a corrective therapy be taken for such a disease? Gene therapy is an attempt to do this. 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 disease. |
Gene therapy method involves: |
Cloning of cells with alternative gene Delivery of normal functional gene in the embryo to compensate for non functional gene Modification of defective genes in the cells cDNA recombination |
Delivery of normal functional gene in the embryo to compensate for non functional gene |
The correct answer is Option (2) → Delivery of normal functional gene in the embryo to compensate for non functional gene |
