BIOL 261 Chapter Notes - Chapter Essay 1: Mitochondrial Dna, Nuclear Material
Document Summary
In 2015, britain became the first country to pass a law permitting three-parent babies from in vitro fertilization. Mitochondrial diseases are caused by genetic faults in dna of tiny structures that provide power to the cell. Mitochondrial defect can cause inherited conditions such as heart problems, brain disorder, lungs and kidney problems and so on. To avoid the risk of transferring of this defected mitochondria to the offspring, a new technique called 3-parent babies in vitro fertilization is introduced which is a cure to many mitochondrial diseases. This treatment involves a mother, father and a donor. A small amount of mothers faulty dna is replaced by the second woman (donors) dna, so that the child will receive genes from two mothers and one father. This method is used just to cure certain genetic diseases and help women to overcome infertility. There are two methods that can be applied to this 3-parent technique: maternal spindle transfer.
