Scientists have promised that gene therapy will be the next big leap for medicine. It's a term that's tossed about regularly, but what is it exactly? Trace shows us how scientists can change your very genetic code.
How does gene therapy work?
"Gene therapy is designed to introduce genetic material into cells to compensate for abnormal genes or to make a beneficial protein. If a mutated gene causes a necessary protein to be faulty or missing, gene therapy may be able to introduce a normal copy of the gene to restore the function of the protein."
Gene therapy trial 'cures children'
"A disease which robs children of the ability to walk and talk has been cured by pioneering gene therapy to correct errors in their DNA, say doctors."
Gene therapy cures diabetic dogs
"Five diabetic beagles no longer needed insulin injections after being given two extra genes, with two of them still alive more than four years later."
