GENETIC MODIFICATION

Mitochondria are the power plants of human cells that convert energy from food, and they carry their own DNA apart from the nuclear DNA in our chromosomes where our genetic information is stored. Only the mother passes on mtDNA to the child, and it occasionally contains mutations that lead to serious problems. According to journal Nature, an estimated 1 in 5,000-10,000 people carry mtDNA with mutations leading to blindness, diabetes, dementia, epilepsy and more. Some of the mutations lead to fatal diseases, like Leigh Syndrome, a rare neurological disorder that emerges in infancy and progressively destroys the ability to think and move.

By combining normal mitochondrial DNA from a donor with the nucleus from a prospective mother’s egg, the newborn is theoretically free from mutations.Researchers have successfully tested this procedure on Rhesus Monkey.

GENETIC MODIFICATION

What is it? Genetic modification is the use of modern biotechnology techniques to change the genes of an organism.Who discovered it?It was first accomplished by Herbert Boyer and Stanley Cohen

When was it discovered?1973Example of Genetic ModificationNew form of in-vitro fertilization (IVF), involving DNA from three parents.The procedure involves replacing mitochondrial DNA (mtDNA) to avoid destructive cell mutations.

FUTHER ELABORATIONWHY IS THIS NEW FORM OF IVF USED?

Method How is it done?

This technology could potentially be used as a measure of prevention to help reduce or completely prevent the illnesses and diseases contracted by babies due to hereditary factors.

Future of the technologyWhat could this mean?
