Approximately 99.8% of our DNA is contained in a cell nucleus, including visible characteristics. These are passed down in equal measure from our biological parents. However there is a small fraction of 37 genes which is located in our mitrochondria, which is inherited from our mother. This new technique which is being developed at Newcastle University hopes to tackle the conditions passed by mothers through gene mutation.
