Focus on genes
The human genome contains 20 000-25 000 genes. What are these genes, and how are they controlled?news
1000 Genomes Project publishes most comprehensive map to date of human genetic variation
Small genetic differences between individuals help explain why some people are at higher risk than others for developing illnesses such as diabetes or cancer. This week, the 1000 Genomes Project, an international public-private consortium, published the most comprehensive map of these genetic variations, estimated to contain approximately 95 per cent of the genetic variation of any person on Earth. 28/10/10
