Three Parent DNA?

Good morning

Fascinating story on NPR this morning about a technique that allows the DNA of three parents to be combined to allow for a healthy child.  This technique is used when there are hereditary defects in mitochondrial DNA.  Essentially the fertilized DNA is stripped out of an embryo and inserted into a donor embryo with healthy mitochondrial DNA.  The hope is that this technique both can lead to a healthy child, and one which, in turn, does not pass on the mitochondrial DNA defects along their own genetic chain.

This procedure is not currently legal in the US.  However, the British Parliament is currently considering changing legislation to allow this procedure.

Have a look at the amazing video of the transfer in process!!
