CRISPR 'gene editing' could lead to 'disease cure'

A technique that allows scientists to accurately edit and rewrite DNA sequences has been developed in the US.

Professor Jennifer Doudna, who helped discover it, believes the technology could one day lead to a cure for some diseases.

It is known as CRISPR, which is an acronym for clusters of regularly interspaced short palindromic repeats.

Professor Doudna explained to the BBC's health editor Fergus Walsh how it works and what impact it could have.
