Question

Which type of gene therapy results in alteration of the DNA of a gamete or a fertilized ovum?

a. Somatic gene therapy
b. Ex vivo gene therapy
c. In situ gene therapy
d. Reversible gene therapy
e. Germline gene therapy

Answer 1

The correct option is: e. Germline gene therapy

Step-by-step explanation:

The germline gene therapy, GGT is the modification of the germ cells. In this therapy, a functional gene is introduced into the genomes of the gametes. Such a modification of the germ cell results in all the cells of the organisms to get modified. This change can therefore be passed on to the next generations. Many countries such as Canada, Germany and Switzerland, have prohibited the use of the germline gene therapy on humans.
