19 December 2016 Current Affairs: The Human Fertilisation and Embryology Authority (HFEA) of the United Kingdom (UK) on 15 December 2016 approved the 3-parent technique.
A 3-parent baby contains Deoxyribonucleic acid (DNA) from three parents. This technique allows parents with rare genetic mutations to have healthy babies by replacing a mother's faulty mitochondrial DNA (mDNA) with another woman's mDNA.
With the present approval, the UK has become the first country in the world to legally approve the controversial medical advancement.
Though Mexico became home to the first baby with this technique in September 2016 itself, the country has no explicit legal stance on this issue so far.
The 3-parent baby technique : Mitochondria are structures in cells which generate vital energy and contain their own set of genes called mDNA.
Mitochondrial diseases are passed through the mother and cause symptoms ranging from poor vision to diabetes and muscle wasting.
The technique involves in vitro fertilization of both the mother's egg and a donor's egg with the father's sperm.
Before these two fertilised eggs begin dividing into an embryo, the unhealthy mother’s egg nucleus is replaced with egg's nucleus of a healthy donor.
This gives the doctors with a fertilised egg with a healthy donor mitochondria and the mother's DNA in the nucleus.
This fertilised egg with the donor’s healthy mitochondria will be implanted in the mother’s uterus.
