A "landmark" project to map 100,000 complete DNA code sequences has been hailed by the Prime Minister, who hopes it will make Britain a world leader in genetic research.
Over the next four years, about 75,000 patients with cancer and rare diseases, plus their close relatives, will have their whole genetic codes, or genomes, sequenced.
Cancer patients will have the DNA of both healthy and tumour cells mapped, making up the 100,000 total.
Scientists expect the project to be pivotal to the development of future personalised treatments based on genetics, with the potential to revolutionise medicine.
