Prominent British scientists blamed the UK government for trying to pass a bill authorizing the creation of „genetically modified babies“ wrote The Independent.
The essence of the claims is limited to the definition of genetic modification, which is used in the government document. In the present form of the document the mitochondrial donor does not appear, because in this case there is no interference in the nuclear DNA.
The essence of the method is that during the process of in vitro fertilization the „spoiled“ mitochondrial DNA in the egg has been replaced by a healthy one taken from another woman. This creates a chimeric egg, where the core (and consequently, the nuclear DNA) has been taken from one woman and the cytoplasm, which contains the mitochondrial DNA, from another.
The child conceived in this way will inherit genetic material from both, and also the paternal nuclear DNA. At the same time the mitochondrial DNA is responsible for less than 0.2% of the human genome, but among other things, it provides the energy metabolism in cells.The violations of this metabolism may lead to serious hereditary diseases.
The method has many opponents who believe that the experiments in this area will lead to a high-tech eugenics and will continue to threat the humanity in the future.
