In the context of the recent advances in human reproductive technology, “Pronuclear Transfer” is used for
- Fertilization of egg in Vitro by the donor sperm
- Genetic modification of sperm-producing cells
- Development of stem cells into functional embryos
- Prevention of mitochondrial diseases in offspring
Explanation
Option (d) is correct
- Pro-nuclear transfer is a technique used to prevent the transmission of mitochondrial diseases from mother to child. This process involves transferring the nuclear DNA from a fertilized egg with defective mitochondria into a donor egg with healthy mitochondria. The resulting embryo, therefore, has healthy mitochondria while retaining the genetic material from the parents, thus reducing the risk of mitochondrial disorders.
