British House of Commons voted to allow the creation of babies with DNA from three people

The House of Commons of Great Britain on February 3, 2015 voted for the bill amending Act Embryology Authority (HFEA), 1990 Human Fertilisation and to allow the creation of babies with DNA from three people.
The donation procedure was controversial mitochondria 382-128 votes. The method includes receiving a small amount of sound called mitochondrial DNA (mDNA) of the donor woman in the usual nuclear DNA from his mother and father.

Now the project has to be approved by the House of Lords, the upper house of Parliament, to implement the donation procedure mitochondria.
If the project is approved, then the UK will become the first country in the world that allows the procedure.

This change in the law of IVF could help 2,500 women of reproductive age in Britain with inherited mitochondrial diseases.

Procedure donation mitochondria:

The process of donating mitochondria includes two different processes.

Procedure 1:

First, an embryo from two eggs fertilized with the sperm of the intended parents and other donors is created.
Then the pronuclei containing the genetic information is eliminated from both parents but only embryos are maintained.
Finally, a healthy embryo is created by adding pronuclei of parents to the donor embryo, which ultimately is implanted in the uterus.

Procedure 2:

First, the eggs are collected both mothers, namely the mother with damaged mitochondria and a donor with healthy mitochondria.
Then, most of the genetic material is removed from both eggs.
Finally, the genetic material of the mother is inserted into a donor egg that can be fertilized by sperm.
What kind of defects can be treated through the procedure?
Generally, defects in mitochondria results in diseases such as muscular dystrophy, heart, kidney and liver failure and various muscle weakness. But the technique could prevent children carry the hereditary problems such as egg or human embryo would be altered before being transferred to the mother.

Why opposes the procedure?

Critics claim that technical crosses a fundamental scientific frontier and changes made in the embryos will be passed on to future generations and lead to the creation of designer babies.
Furthermore, the Catholic and Anglican in England, say the idea of ​​procedure unsafe or unethical as it involved the destruction of human embryos.
Comment
