An AI model developed by Google's DeepMind could transform our understanding of DNA - the complete recipe for building and running the human body - and its impact on disease and medicine discovery, according to researchers. The remaining 98%, which is less well understood, is labelled the 'dark genome'. AlphaGenome can analyse one million letters of code at a time, helping to unravel the 'dark genome'. The AI model could be used to "add another piece of the puzzle for the discovery of drug targets and ultimately the development of new drugs", she added. There is general agreement that the AI model needs refining.
